Sweet-Blood by Pete Hautman

() What do you get when you combine a goth-phased, vampire-obsessed, teenage girl with a bored, diabetic, espresso-fiend? You get this Lucy chick. She's so smart she's even developed her own clever theory about the evolution of the legendary vampire myth. She believes 'vampires' developed from early age diabetics that existed before it was diagnosed as an illness. Her argument is very convincing.
She, in turn, is very convinced by a much, much older man she met on the internet who claims to be a "real" vampire. This is where the real struggle in the story is displayed.
Interesting, suspenseful, and horrifyingly easy to relate to. It's incredibly creative and well-researched. Definitely worth checking out.

Excerpt from pg. 1 of Chapter 1: Blood; "Blood is my friend. Without it my cells shrivel. Without it I die. / At night, alone with myself, I hear it rushing through arteries and veins, platelets tumbling in a soup of plasma and glucose through slick, twisty tubes, lining up to enter narrow capillaries, delivering oxygen and fuel, seeking idle insulin. It is a low-pitched sound: wind passing through the woodlands. / I hear a higher pitched sound too: A demon dentist drilling, rising and falling but never stopping. It is the sound of my thoughts. / Alone, at night, with myself, the low sound and the high sound become music."
