This was an entertaining read, despite finding some of the behaviour by the characters to be somewhat unrealistic. I was surprised to find it described as a thriller, as I would say it is more a character driven tale of best friends, manipulation and romance. I particularly enjoyed the early friendship years. The book within a book and multiple POVs worked well and there were some nice humorous moments. Thanks to Edelweiss+ for the ARC. 4/5 stars
