If my only consideration is if I liked the book, I would have given this five stars. The plot was meaty enough, typical of a thriller; the financial aspects were juicy (some sections could even be used as learning material). I loved every second of reading it.
Unfortunately, the book suffers the same fate as the typical thriller. In fact it does more than that: it reads like your average telenovela. The MC was what?? And the sister?? And two of the siblings did what with the same guy?? And of course we get the inevitable chase scene, complete with the quite capable MC. Near the end I kept rolling my eyes at the obvious structure and the clear-as-day character traits (while enjoying the read, mind).
Still, if you can get this for cheap, I'd recommend the book. I have several more Frey novels in my unread stack, which should be fun.
