Ugh. This book was very readable, and I raced through the last half to find out what happened - so points for that. But it's a domestic-thriller-by-numbers really, with the "twists" were signposted from early on and the characters very 2 dimensional. It's an easy read but ultimately I feel my time would have been better spent on something else!

Slightly fuller review with spoilers.

Wally was the least 2D character, but he was also "too good to be true" in a lot of ways. Kind and accepting AND super rich! How handy. What really got this book down to a 2 star rather than a 3 for me though was the use of the very boring trope of allistic authors writing an autistic-coded character as a plot device*. I'm so sick of it now, and this was a real cardboard-cutout version of it too (I had the same issue with The Maid). Also, there's a bit where Rose is described as "narcissistic, maybe even Borderline Personality Disorder" as if people with BPD are automatically Really Bad Scary People. BPD is a stigmatising enough condition without nonsense like this being spread about it (and it's not even officially called that anymore). In short, a book with mental health and neurodiversity as central themes, written by someone who seems to lack any real knowledge of them.
* I did guess this from the book's description/synopsis, but hoped it would be well-executed. It wasn't.
