Dream a Little Dream (Silver Trilogy)

Mysterious doors with lizard-head knobs. Talking stone statues. A crazy girl with a hatchet. Yes, Liv's dreams have been pretty weird lately. Especially the one where she's in a graveyard at night, watching four boys conduct dark magic rituals.
The strangest part is that Liv recognizes the boys in her dream. They're classmates from her new school in London, the school where she's starting over because her mom has moved them to a new country (again). But what's really scaring Liv is that the dream boys seem to know things about her in real life, things they couldn't possibly know-unless they actually are in her dreams? Luckily, Liv never could resist a good mystery, and all four of those boys are pretty cute....
