Mmm, where to begin. Firstly, if someone tells you this is something like Lee Childs Reacher novels, it isn't true.
But did I like the book? And I must admit I'm struggling with this. The lead character isn't someone to sympathise with, in fact, he isn't very pleasant. He works for the CIA and works in counter terrorism, which seems fine, but then he also takes on contracts to wack people from crime bosses. It's the latter of these which causes the issue, he's killing "nice" people, just for the money.
Somehow, it does make it rather unpalletable, especially after the extreme opposite of the way he treats his daughter.
I don't want to give too much away, but it's a bizarre story, hard to love, but entertaining at the same time.
I think it's like marmite, you'll either love it or hate it. Perhaps try the sample first to see if it's to your taste.
