Darkside by S.K.S. Perry (no relation to yours truly), if not exactly light, is quite witty, fast-paced, and seriously genre-bending. The story is about a guy named James Decker who dies in the process of saving a young woman from being attacked. But he finds that he really isn't dead...well, sort of.
From the blurb:
Haunted by the ghosts of his father and grandfather, [James Decker] learns that the woman he rescued is in fact an Innocent, the physical embodiment of hope. As it turns out, seeing dead people is the least of James' worries. It's the trolls, goblins, vampires, and other assorted creepy-crawlies that make being dead a living nightmare.
Turns out Darkside is what all these dark creatures living in the Otherworld call our reality. And that's just one of the rules of the afterlife James has to learn as he finds a new lease on life protecting the Innocent from further harm. With wry humor and snide first person remarks, Perry transports you from one realm to the other and back again in a quest you'll not likely forget - if you don't die laughing first. A bit slow in the middle, but overall, a solid debut novel.
The frolicking adventure continues in Darkside: Waking the Dead, which I just loaded on my Kindle! By the way, Darkside, first novel is available for only 99 cents!
