AN INSTANT NEW YORK TIMES BESTSELLER

Three girls, one supernatural killer on the loose . . .

Zara Jones believes in magic because the alternative is too painful to consider—that her murdered sister is gone forever and there is nothing she can do about it. Rather than grieving and moving on, Zara decides she will do whatever it takes to claw her sister back from the grave—even trading in the occult.

Jude Wolf may be the daughter of a billionaire, but she is also undeniably cursed. After a deal with a demon went horribly wrong, her soul has been slowly turning necrotic. It’s a miserable existence marred by pain, sickness, and monstrous things that taunt her in the night. Now that she’s glimpsed what’s beyond the veil, Jude’s desperate to find someone to undo the damage she’s done to herself.

Enter Emer Byrne, an orphaned witch with a dark past and a deadly power, a.k.a. the solution to both Zara’s and Jude’s problems. Though Emer lives a hardscrabble life, she gives away her most valuable asset—her invocations—to women in desperate situations who are willing to sacrifice a piece of their soul in exchange for a scrap of power. Zara and Jude are willing, but they first have to find Emer.

When Emer’s clients start turning up dead all over London, a vital clue leads Zara and Jude right to her. If a serial killer is targeting her clients, Emer wants to know why—and to stop them. She strikes a tenuous alliance with Zara and Jude to hunt a killer before they are next on his list, even if she can’t give them in return what Zara and Jude want most: a sister and a soul.

A wonderful primer for those discovering the amazing world of generative AI
Format: Paperback, Format: Paperback
Somewhere in the past year, ChatGPT has gone from "cool, interesting, amusing" to a massively valuable work assistant capable of writing Python scripts, analysing data, and doing lots, lots, more. The key to this? The rapid evolution of OpenAI's GPT models and making my first forays into prompt engineering. If I thought I was getting good, though, this book took me reminded me that I'm just scratching the surface. Halfway through the first chapter I was already furiously scribbling notes in the margins for what I could do better with my prompt writing and by the end of the text I felt like I had gotten a very good grounding - not just in GPTs specifically but in the bigger picture of how these hugely powerful tools were trained and came to maturity. I imagine that few will argue with my assertion that there is lots of hyperbole and "noise" in the AI space right now which, as ever, makes it hard to pick out the signal from the noise. Which is precisely why I sought out an O'Reilly title and I'm very glad that I did. Thorough, excellent, and I hope that this edition will be the first of many. As this rapidly maturing field scales and matures I think that prompt engineering will be an essential discipline to master. Pick up this text to get a good foothold on things.

Understanding AI prompts as a science
Format: Audiobook
Prompt engineering is the art and science of finding the right words to generate the right responses from artificial intelligence (AI). It's becoming a skill in-demand in today's workplaces. It's also becoming an essential skill for life. To understand prompt engineering, you must understand how AI tools understand their inputs. This book explains that to you in many forms. It covers prompting as it intersects all the major AI disciplines, like general prompts (as in a ChatBot), fine-tuning, and retrieval-augmented generation (RAG). It also introduces how prompting intersects a couple of image-generation tools. As a scientist, I appreciate the theoretical approach to these practical matters. Too many people are hacks at AI these days, and any technical understanding can rapidly advance an individual's effectiveness. Prompt engineering is often made fun of as a "soft" topic, but as this book demonstrates, it intersects all the major AI areas. Presumably less garbage in means less garbage out. This book shows how you can make that take place. As typical for O'Reilly materials, this book appeals to people who desire an intermediate-to-advanced understanding of how AI works. It's not for the casual user. Anyone technical involved in professional knowledge generation using AI can benefit from understanding the dynamics "under the hood." It's a good, though perhaps not ground-breaking, textbook for those of us unable to take a class in the subject. Prompt engineering may be a soft topic to many, but books like this ground the field in the science that can make or break a digital or software product.
