Gemini Bites by Patrick Ryan
Its kind of a funny story....
Storyline: One of the strangest (and funniest) love triangles ever to hit YA fiction, when a pair of twins (one boy, one girl) both fall for the boy who moves in with them…who may or may not be a vampire.
Judy and Kyle Renneker are sixteen-year-old fraternal twins in a rambling family of nine. They have a prickly history with each other and are, at least from Judy's perspective, constantly in fierce competition. Kyle has recently come out of the closet to his family and feels he might never know what it's like to date a guy. Judy, who has a history of pretending to be something she isn't in order to get what she wants, is pretending to be born-again in order to land a boyfriend who heads his own bible study.
When their parents announce that the family is going to be taking in a fellow student for a month so that he can finish the school year before moving away, both Kyle and Judy can't help but sit up and take notice. Garret Johnson, who is taking temporary residence in the newly finished attic, is a young man who moved into town less than a year ago and who is a mysterious, goth loner . . . and claims to be a vampire. He's not an easy person to get to know by any means, but the twins find him (to varying degrees) both strange and alluring.
GEMINI BITES explores what it means to pretend to be something you aren't, what happens when that backfires, and how in-your-face honesty is almost always the best course of action.
Patrick Lynch has written some reads you may have already read. The Saints of Augustine and In Mike We Trust, as well as the adult novel Send Me.
Seriously, I think Lynch is the only one who could make this strange story so real with his way of story-telling. Its a new kind of page turner. Wondering just how far this story will go.
