I found it quite gripping and entertaining. I read in two setting as I wanted to know what was going to happen and the next twist.
I think that the characters are well thought but I didn't like Karen Willis: she's an interesting character but I was wondering if some imperfection could make her more likable. In this book she seems a sort of "perfect woman" and some imperfection would help.
I rooted for the underdog, Tony Allen. Even if he's in the background he's also the one that makes the most relevant discovery.
The plot is full of twists and turns but the solution seemed a bit rushed and was sort of "out the blue".
I'm curious to read other stories featuring these characters.
Many thanks to the publisher and Edelweiss for this ARC, all opinions are mine
