I don't even know how much time it took me to read this book as I started and stopped a few times before I committed myself into it. Something about Ricardo and August/Augustus didn't "work" for me. They spent most of the book quarreling with one another disagreeing about anything and everything. The attraction was always there - I got that and I actually really appreciated that it took them time to act upon it. The book was very suspenseful but the real action started I think round 70% in and didn't stop right until the end which is when I got REALLY invested in the story.
If you look at the almost satirical website "Rate Your Hit" you'd find the best hitman out there is Ricardo Torralba and right under him is August Morrison. This might look like the kind of website to have a good laugh about but it's actually genuine. But when Ricardo and August find themselves on the same job to off billionaire Lance Baldwin they feel like something is wrong. So very wrong.
They run without finishing the job only to realize that since they didn't off each other whomever put them on the job is more than willing to finish it on his own. That means that though they're not exactly team players they need to work together and learn to trust one another and FAST.
