Mercer, Sienna.

My Sister the Vampire: Twin-tastrophe / Sienna Mercer. - New York : Scholastic, 2012, c2011. - 177 p. ; 20 cm. - My sister the vampire ; 9. .

Ivy has a coffin-sized secret -- and she's been expressly forbidden by the vampire-powers-that-be not to share it with the one person she's dying to tell - Olivia. Ivy and Olivia certainly have their differences, but they've never let things like a set of fangs, or a fondness for bats, threaten their friendship. They're twins after all, and nothing could ever come between them - could it?
