Based on the summary, I had high hopes, but the book didn't live up to its potential. Things felt very rushed. As a result, the character development was a bit lacking, and the killer's motivations didn't make much sense. Character voices weren't as distinct as they could've/should've been (specifically Ellie and Stella). The book had the potential to use the traumatic events in a way that could have been quite relatable and meaningful to those who've gone through a trauma, but it didn't. The author attempted to tackle a number of relevant issues (race, gender, addiction, etc), but more could've been done, particularly with the mental health aspect. The big "reveal" was lackluster. I enjoy this genre, in general, but I really struggled with this one, and I found myself skimming at times in the hopes it'd pick up and redeem itself. Sadly, it didn't.
