First Grave On The Right - Number 1 in series

Private investigator Charlotte Davidson was born with three things: looks; a healthy respect for the male anatomy; and the rather odd job title of grim reaper. Since the age of five, she has been helping the departed solve the mysteries of their deaths so they can cross. Thus, when three lawyers from the same law firm are murdered, they come to her to find their killer. In the meantime, Charley's dealing with a being more powerful - and definitely sexier - than any spectre she's ever come across before.
With the help of a pain-in-the-ass skip tracer, a dead pubescent gangbanger named Angel, and a lifetime supply of sarcasm, Charley sets out to solve the highest profile case of the year and discovers that dodging bullets isn't nearly as dangerous as falling in love.
