This book is perfect for a fun little binge read but not more then that.
It's funny, very fast paced and the real life escape room concept was very well written. However the character's are super blunt and not flashed out. Throughout the book I barely managed to tell them apart. They all felt like the same person and honestly it didn't even matter who was who.
The plot is also nothing crazy or mindblowing. It's actually a pretty basic plot twist and if you are someone who's read a few thrillers you will have read atleast one book with the exact same outcome. 
Nevertheless I don't regret reading this and it was an enjoyable quick read.
