Leslie Langtry has a series in which she describes the Bombay family. A family of hitmen and I guess hitwomen now that I think of it... is hitwoman a word? I need a videogame to be sure :)
Anyway, I love the premise of this series which includes other romantic works such as "I Shot You Babe" and "Guns Will Keep Us Together."
These are campy romances but the sarcastic hitman lifestyle makes these worth a read.
I think what also earned the author a little of my respect were the quotes in the beginning of the chapters from various pop culture sources like "Kids in the Hall" and the movie '300.'
So don't expect to be blown away by these books and they are more for the female reader with the romances but these are great for a short entertaining jaunt into fantasy land.
If you liked the Movie the "Whole Nine Yards" you might like these books. That is the best I can compare it too. I won't say "Grosse Point Blank" because that is a cult hit that should be revered... although it is quoted in these books :)
