MUST Read for any age.
Format: Paperback
I read this book as a sophomore in college for a unit on banned books. Knowing that there is a generation of students who won't get to read this book and think about/discuss the themes Lo presents is devastating. Despite the debates surrounding the book’s appropriateness for younger kids, I believe this book is EXACTLY what children need to be reading. Specifically, I think middle school-aged children could gain a lot of value in reading this book to help them understand sexuality, relationships with family and friends, and that not everything is as black and white as some people may believe. Lily and Kath’s relationship is written so beautifully, and as a reader, it felt real.
Even though I would categorize this as a YA novel, anyone at any age can gain a lot from reading this. The story is captivating and real. Lily (the main character) doesn't get everything she wants, and while the ending is somewhat satisfactory, it leaves the reader wanting to know more, which I think has its pros and cons. Personally, I liked the general ending, but to be honest, I wanted to know more about what ended up happening regarding some of the storylines of the book. For example, Lily’s father had some issues regarding his immigrant status. We hear bits and pieces here and there, but we never really find out if/how it gets solved. Relationships like Lily and Tommy’s (a performer at the Telegraph Club) spark interesting conversations about power dynamics and where the line is between nurturing and overstepping.
I understand parents, guardians, and teachers may be worried about “exposing” children to “difficult” content and discussing things like sexuality with young individuals. But in my opinion, books like this are the perfect way to lay the groundwork for those types of conversations. We are delivered messages and lessons through an interesting story with layers about what it is like to be a teenage girl in a World of uncertainty– something I think many can relate to. Please read. Please give to your children to read. Please don't let this book be erased.

sweet tale of a child of immigrant parents figuring out her own truth
Format: Kindle
1950's San Francisco Chinatown is complicated enough for second generation Chinese teenagers, what with racism whenever they leave their safe neighborhoods, the Nationalists vs Communists entangling families in politics, and the ever present Red Scare excusing blatant police and enforcement inequities.
Imagine falling in love with a white person of your own gender at that time.
Lily is fascinated by the ad for a male impersonator at a local club. When she realizes the only other girl in her advanced math class also likes that ad, she begins sneaking out of her house and her "good Chinese daughter" persona to hang out in a club where terms like "butch" and "dyke" show her another world where women like her live and love.
Lily is naive, and loving, and just wants to do the right thing, but she'll have to face the constant choice of living true to herself or telling lies to appease her family.
The romance in this is understated and reserved, and its far more a historical exploration of 1950's Chinatown culture and the most interesting (to me ) intersection of cultures where the second generation children of immigrant parents must negotiate their identities within conflicting expectations. Lily is part of a large extended family that includes close knit families of Chinatown and her actions have repercussions on many people-- including her non-citizen father.
I didn't personally care for the sudden changes in POV to Lily's mother and Aunt...they added little to the tale I thought and their voices were too similar to Lily's to be interesting to me. I found myself skimming those bits to get back to Lily. The addition of timelines with historical and Lily's family events were interesting, but also confusing as the flashbacks jumped back and forth.
Very historically interesting, sweet, tale that keeps you anxious for Lily's welfare but never goes down a truly dark path.

One of the Best Books Ive ever read.
Format: Paperback
I read this last January and it was amazing, it was one of the best books I have ever read in my life, it was really sad at times but it was perfectly written, and the story was amazing. It made me by other books by Malinda Lo, she is a very great author.

Historically accurate, coming of age queer love story.
Format: Paperback
A beautifully written, historically accurate coming of age queer love story.
The author even includes in the end a section discussing why she uses the language she does. This is a really good glimpse into the realities of queerness in the '50s and it wasn't all pretty. The unique viewpoint of Asian American life in the '50s prompted some history deep diving on my end and I love when a book prompts further interest in topics you realize you knew very little about. We're all so absorbed in our own worlds and it was a pleasure getting to glimpse into another world that wasn't actually another world at all.
Wonderful young adult read.

An amazing story not to be missed!
Format: Kindle
This just might be my most favorite book of the year! I know we’re only in February, but still! This has long been waiting on my TBR pile and I could kick myself for taking so long to pick this up.
This is a YA historical sapphic tale set in 1950s San Francisco. Lily a high school senior is the epitome of a “good Chinese girl” responsible and respectful. Her world is thrown into a tailspin when she realizes that she likes girls. Accompanying her in this discovery is Kath, a fellow senior and together they find “themselves” under the heady atmosphere of the Telegraph Club.
There was so much to love about this book from the authenticity of the backdrop to the incredibly sweet romance playing out. Malinda Lo has clearly done a ton of research (check out her Author’s note, it’s amazing), you can see it come to life in the rich description of the city, the smokey club, the character mannerisms and interactions. All of which have that ring of reality to it and serves to completely immerse you in that time period.
I loved how Lo slowly built out Lily’s affirmation of who she is from feeling initially guilty about her attraction, to being brave enough to seek out the Telegraph Club to proudly standing up to her beliefs and her love for Kath.
There are lots of side characters and side stories, all serving the purpose of highlighting the political climate, drama and mental makeup of the characters. But my favorite was Lily’s aunt and role model Judy. Her last line “I don’t understand what you’ve been going through, but you’ll just have to put up with me until I do understand.” was just perfect and you know inside that Lily would be okay with Judy in her corner.
That last portion of the book is a lip wobbler so get ready coz it packs a punch and that epilogue was just pure class. No saccharine HEA but something filled with lots of love and hope. The hype is well deserved! So don’t put it off anymore just go read it! Easily 5🌟s
