Then She Vanishes is a very good mystery, I think on par with 'The Return of Ellie Black' and leagues ahead of 'The Nanny' other Thriller/Mysteries I've read in the last few months.
Trigger warnings: Murder, Gun Violence, Drugging, Drug Addiction, Kidnapping, Prolonged Captivity(Mentioned), Stroke, Grooming, Stalking, Physical Abuse(off page), Emotional and Verbal Abuse, Neglect of a child(Mentioned), Rape/Sexual Assault(Mentioned/Theorized), Pedophilia

This was not has heavy as Ellie Black because we don't spend as much time with a victim as we do with Ellie, but deals with some of the same subject matter that Ellie Black does. Such as the kidnapping and prolonged captivity of underage girls (Ellie was 14 and Flora 16). As it's not as heavy, it's easier to consume, especially for people who are sensitive to the abuse that takes place in these stories.

The mystery itself is well crafted, and had me waffling between a few ideas, with one serious red herring in there. I was confident the whole time Heather did kill those people, but it was a brilliant choice to have two of the POVs read by the same actress to keep the beginning obscure. I was also absolutely certain we were going a different way, and there was going to be a serious discussion to be had about older men/teenagers grooming younger teens into things like drugs. Because we did start slowly with weed, then moved to coke and other harder drugs by the end. But the grooming sorta stopped and isn't the through line of the whole mystery.

Jack is my absolutely favorite character, he's got a sort of charisma that jumps off the page and you feel very endeared to him right away. I enjoyed deeply he's gay and that's really not a big deal ever, but he sorta drops off the page and is got a pretty good chunk with Jess worried about what he might be doing to sabotage her career instead of wondering if he's okay, if something happened after he got mugged. Also, google 40% of cops :) just for fun. Trust me, you'll have a great time learning about what 40% of cops are :)

Margo is my favorite of the POV characters, how dedicated she is to her daughters and Jess is lovely. I was worried about this being a story about everyone hating Jess and then they switch suddenly at the end, but it wasn't. Margo warms to Jess pretty quickly and finds comfort in these trying times with Jess. Her grief and her emotions are palpable as Flora haunts her and the narrative.

With a well thought out mystery, you really want to keep the reader guessing, and guess I did! A lot! and was wrong... A lot! But in the end, I was right all along :)

also her uncle is a nonce, send his ass to jail too!!!
