Pretty good
Format: Hardcover
In 1932, Lulu Wong made a name for herself by leaving Chinatown and becoming a Hollywood star. Most girls who look like her don't get lead roles, so Lulu is the pride of her neighborhood. So everyone is shocked when Lulu's body is found in a local stable far from her Beverly Hills home by her friends, sisters May and Gemma. The girls know that the police won't look too hard into the murder, so they decide to take matters into their own hands. As they investigate, the sisters discover a plot to frame Chinatown as a den of iniquity that should be demolished in favor of constructing a new train station. May and Gemma soon find themselves in a race against time to not only find justice for their friend but save their neighborhood, all while being targeted by a killer.
I've only read a few books by Lee, but they've all been winners. I love her style when it comes to YA historical fiction. She crafts compelling plotlines that include real issues of the time with characters you can't help but root for. I liked both our main characters. May was more logical and reserved, while Gemma was a spitfire, but they balanced each other perfectly. I liked how we got both of their POVs, but I did enjoy Gemma's slightly more because I loved her gumption. I thought the mystery was well-paced and kept me intrigued. I had no clue how it would play out, and I liked how Lee wrapped it all up. It did drag a bit in the middle, but overall, I thought it was entertaining.

not as good but nearly there
Format: Kindle
I had hoped that Kill Her Twice would grab my attention in the first few pages and not let go till the very end (like her other books I have read), but this one had a very. Slow. Start.
The mystery of the death of a young Chinese starlet in California in the early 1900’s is the catalyst that starts everything: new characters are continuously introduced, their motivations becoming clear and murky and clear again several times before the last quarter of the book. But. The last quarter (finally) had me hooked.

YA historical murder mystery
Format: Hardcover
3.5 stars
What I Liked:
-Character voices seems to be once of Lee's writing strengths. From the start of the book, Gemma and May's voices sparkle on the pages. Gemma herself seemed to be a little stronger of a character, but I think that's because she had a more spunky, active personality.
-The positive sister relationship made me happy. So often, I feel like siblings don't appear in fiction, or if they do they just fight with each other. I liked how all of the Chow sisters worked together, and the positive family relationships in general.
What I Struggled With:
-Something about the mystery fell flat and I was left wanting more. I can't pin my finger on exactly why I felt that way, but it might have had to do with how Gemma and May solved the murder. They honestly don't really see it coming or put together many clues until the end. When the murderer revealed everything, I could see the crumbs that had been foreshadowed--but I think that they needed something /more/ to make them work.
- I'm glad that Gemma and Freddie didn't end up together. I'm not entirely sure of what the age difference was, but since he'd already graduated med school and seemed to have been a doctor for a while, I'm guessing it was fairly large. Because of the age gap, I was a little uncomfortable with the relationship that seemed to grow between them. I don't think it would have bothered me if just Gemma had a crush, but Freddie seemed to like her as well. But as I already said, they don't end up together.
Overall:
I enjoyed Kill Her Twice. But I was a little disappointed in mystery side of it. Yes, Gemma and May are solving a murder, but the mystery seemed to fall a little flat. However, Lee's abilities in writing characters shine.
Cautions: three instances of swearing; one blasphemy; light romance; one kiss; brief, moderate violence; non-descriptive mentions of poisoning; two minor characters are discovered to be gay, referenced briefly; an unmarried character is discovered to have been pregnant, which is referenced multiple times ; several Bible verses are taken out of context and twisted
(I received an eARC through NetGalley. All thoughts are my own.)

Hollywood Murder Mystery
Format: Hardcover
This book is a captivating murder mystery set in 1932 Los Angeles. Chinese American sisters Gemma and May have a lot to worry about their mother is pregnant and their father is away getting treatment for an illness, then they have to run the family flower selling business, and their home in Chinatown will likely be destroyed to build Union Station. The last thing they needed was to find the body of Hollywood starlet and May’s friend, Lulu Wong. Not trusting the police to investigate especially when the police frame a homeless man from Chinatown, Gemma, May and their little sister Peony try to solve the murder themselves. They start looking into the people in Lulu’s life and who would have a motive to kill her. Another actress, a co-star, a rich man who hates Chinatown, a possible secret boyfriend, Lulu’s agent, extras in the film, and her new film’s director are all suspects. Gemma comes up with schemes to find information, May starts working on the movie Lulu was filming, and Peony talks with Lulu’s little sister. They also get help from Wallace, a young entomologist, and Freddie, a young doctor. As the sisters uncover more secrets, more the dangerous their investigation becomes and they are putting a target on their backs. With so many suspects and red herrings, will the sisters find Lulu’s killer?
This story has a fast pace with lots of twists and big reveals in the sisters’ investigation. The story is told in first person alternating between Gemma and May. Gemma is a big dreamer with lots of ideas and is a bold, risk taker. May, the oldest sister, is more practical, cautious, and careful. The other characters are great and well written. The 1932 Los Angeles setting is well researched and described. The story has a bit of romance between May and Wallace and a flirtation been Gemma and Freddie. The ending wraps up the story, we learn Lulu died and who was her killer and the next step in the sisters’ lives. The cover is beautiful and I really enjoyed this book. Fans of historical mysteries like the Stalking Jack the Ripper series, the Jane Austen Murder Mystery series, and the Burning Cove series would like this book. Another excellent read by Stacey Lee.
