Shades of Atlantis — Carol Oates

Since the death of their parents, Triona Pryor and her brother, Ben, have lived with their aunt and uncle in Camden, Maine. Now in her senior year of high school, Triona loves her family and friends, but she has always felt that she didn't quite fit in...in Camden, or anywhere else. Enter Caleb Wallace, the devilishly handsome man who has recently moved to Triona's small town. While their attraction to each other is instantaneous, it also proves to be dangerous...and deadly. When tragedy strikes, Triona flees to London for solace and to start her life anew. It's there she discovers from an unlikely source that her family has been keeping secrets from her - secrets about not only her birthright, but her ultimate destiny as well. Armed with this knowledge, Triona finds herself thrown into a whole new world and into a battle to save the lives of everyone she loves.
