Query: Continues a great series.

Bloodlust, the second book in the Vampire Twins series, was just as good as the first. Ari and Paul's closeness is further threatened as Ari becomes closer to her boyfriend, Cos, and Paul, in an impulsive moment, becomes a vampire. He vows never to threaten his own sister, but his lust for blood may be more powerful than his love for her. I highly reccomend this series to teens who love horror stories.
