Mac Plus 12/24-30 + CZone

Boost the Service Battery

Too often, service batteries don’t get the charge they need. This is a problem made worse by smart alternators and start/stop systems, which result in slow and insufficient charges. The Mac Plus DC-DC charger solves this problem, providing a quick, safe, and consistent charge to the service battery. And, by knowing when the engine is running and providing charge, users can be sure that the Mac Plus will never drain a starter battery.

Proven Mastervolt Quality

Users get peace of mind knowing that they have the best on board. Using the proven Mastervolt 3-step+ charge algorithm, the Mac Plus delivers a quick and easy charge, even for completely flat batteries.

A robust design holds up in even the harshest conditions, with battery temperature-optimized charging and a high-quality aluminum housing to ensure superior protection against dust and water ingress. The power-efficient design also allows the Mac Plus to operate silently and without a fan.

Total Power Flexibility

He falls fast & hard, but she’s trying to slip away..
Sadie Brown has herself so thin taking care of everything around her she’s on the verge of losing her college figure skating scholarship. She’s juggling being the parent figure to her two younger brothers (alcoholic father), working 2 jobs, figure skating, college classes, & trying to have somewhat of a social life. So to maintain her figure skating skill, Sadie skates early in the morning before anyone should be at the rink… Rhys Koteskiy, college hockey captain, and son of famous former NHL player Maximilian Koteskiy. Thinks he’s on top of the world in his growing career, until one day he takes a nasty hit that leaves emotionally unable to get back onto the ice without complete panic. When he decides to try and take control at the rink alone so others don’t find out about his anxious state, he runs into the angsty figure skater… Their paths keep connecting from the morning skates where they decide to share the ice from Sadie’s brothers participating in the youth hockey program Rhys helps out with. Sharing music playlists turns into sharing each others bodies for each others personal gain. But what happens when the guy falls first and the girl wants none of the emotional strings? Or when lawyers become involved with Sadie’s situation of her brothers? Buckle up because it’s about to become quite icy! 📚 College Hockey Romance 📚 Forced Proximity 📚 Single Parent / Sister 📚 Angsty!! 📚 Secret Friends With Benefits 📚 He falls first & HARD 📚 Dual POV This was my first read by Peyton Corrine & omgsh I loved it! Such an emotional read covering heavy topics of male anxiety / mental health & the Cinderella sister. A beautiful approach to such real everyday topics that don’t always get talked about. I can’t wait to read more of her work!!

Unsteady by Peyton Corinne
Format: Kindle
» The blue - Gracie Abrams « 0:00 ─〇───── 5:00 ↻ ◁ II ▷ ↺ · The way I feel about her is real, so deep it feels like a cord looped from inside me to her, tethering me to her. · This series is everything to me! The way Peyton Corinne incorporates mental health into all of her books is so special and important. The representation is always so good, and you can clearly tell that she puts a lot of effort and research into making things accurate. This book was so insanely addicting and fast-paced. It was a super quick and easy read, and I always thought about it when I wasn't actively reading it. Rhys Koteskiy, the man that you are. I'm going to be honest: at first, I wasn't sure I was going to enjoy this book because it was very much insta-love for him, but I think it was drawn out very well, and I also think it worked for his character development (iykyk). The way that he treated Sadie and showed her that constant reassurance that he was never leaving was so special. Not only was he a great love interest, but his healing from page 1 to 360 was incredible, and I think that if you're an athlete who has gone through injury and/or is struggling with an injury, the representation is HUGE. To be completely honest, I don't have much to say about her, but I absolutely loved Sadie, and I felt for her so much! This last note honestly doesn't have anything to do with the book or the author, but the comparison between Binding 13/Johnny and Shannon does a huge disservice to the book and creates a false expectation for the reader. All of this being said, I highly recommend this book and will certainly be reading all of Peyton's work!

The Best Starter Writing Book Out There
Format: Kindle
Anyone who's serious about writing a book needs to start here. Gardner's advice on maintaining the "fictional dream" for the reader--that is, suspension of disbelief, immersion--is top notch. Part I, the discussion and overview of fiction, is engaging and helps contextualize the advice presented: where on the spectrum of the written word we are trying to fit into, what it aims to accomplish, what it needs to accomplish that, and how we go about creating it as writers. Part II covers the common pitfalls and offers technical advice. Style and structure are covered, with especially good lessons on diction and proper sequencing of signals in the test (stimulus, involuntary reaction, voluntary reaction--which may be thought of as cause & effect and is explained in greater depth in Dwight V. Swain's book as Motivation-Reaction Units), with solid explanations for why mistakes here harm the fictional dream and why it is important to get it right. Also covered are the "clumsy writing" mistakes such as characters looking in mirrors to shoehorn description into the text, as well as melodrama, which relies on cheap sleight of hand in writing as opposed to real drama. I loved the section on vocabulary, which explained the problem with writing-by-thesaurus while emphasizing the importance of expanding ordinary vocabulary that include more uncommon words (such as technical architectural terms like "lintel," which, while uncommon, are a benefit to writing) as well as brand names. What this book will do: - Give you a good overview of fiction - Help you understand what fiction tries to accomplish, why, and how - Explain the common clumsy mistakes and how to avoid them - Provide you exercises - Entertain you with Gardner's engaging writing voice (so it doesn't feel like a manual) What this book won't do: - Help you understand nonfiction and how to write it - Cover the common mistakes in-depth - Give you genre-specific advice - Cover anything related to self-publishing - Explain the business of writing - Take the place of critiquers, beta readers, or editors This is a great intro to writing craft book. It should, at the very least, help you understand what you're trying to do and identify your weaknesses so that you may find more narrowly tailored resources to help you. I find myself referring to the passages I highlighted quite often, both in the paperback and the Kindle version. FWIW, the Kindle version is now searchable. When I first bought it, it was not. The search function is a *great* help.

This is a must read for ALL writers, not just fiction writers!
Format: Paperback
This is a must read for ALL writers, not just fiction writers! Although, in places, a bit technical, for any writer, not just new writers, for anyone who wants to master their craft, this is a must read book. What can be said about Gardner that hasn't been said yet? One of the best books on writing about writing that I have read. Comparable to Stephen King's, On Writing. Yes, it is that good. In Part I Gardner lays out a compelling treatise about the genre of fiction, what it is and why it is important. In Part II he discusses the how-to of writing good fiction, where he talks about common errors, technique and plotting at length. One of the benefits from reading The Art of Fiction is that it gives the reader a crash course in literature, who many of us that come from a Science, Technical, Engineering and Math (STEM) background are sorely lacking in. This said a writer who has grown up in the sciences, or engineering, or business worlds will find this book very useful in "catching up" a bit to our friends who have read all of classics and can retell significant scenes as though they were there. Again, this is a must (must) read for ALL writers, not just fiction writers.

Format: Hardcover
The book itself is excellent, very helpful with lots of specific information. I was disappointed (one star) that the used hardcover edition I ordered arrived as the paperback edition, though in very good condition.
