I'd do nothing but reading if I could (ok, maybe eat some great food, buy some fancy shoes between two books...oh, and spend some quality time with the gorgeous guy I married while I am on reading-break anyway...)
This lacks a bit in the romance department, but has action galore, a solid and interesting (if not totally original) world-building, a very cool and fascinating protagonist and a quite high body count.
What I liked most, was that Nathan really really was a bad ass.
In the end even more than in the beginning...he is what I would expect an assassin to be.
One with some morals, but still willing to kill all that stands in his way.
And for 0.99 Euro a real bargain!
