Marked is the first novel in the House of Night series written by P.C. Cast and her daughter, Kristin Cast. As a years-long, die-hard fan of L.J. Smith's The Vampire Diaries, I typically tend to shy away from most other teen vampire series (because I'm just never satisfied!). But after having purchased the first several books in the House of Night series for a bargain, I decided to give it a whirl.
