Synopsis from Goodreads

When a supernatural freak of nature forces her family to separate, seventeen-year-old Charlie Page must turn to her frustrating (yet gorgeous) neighbor, Seth, to help reunite them. Seth whisks Charlie to Ellauria—a magical world filled with the creatures of myths and legends—and tells her of the Fellowship, the group charged with protecting mystical beings from human discovery. (All except Bigfoot: that attention whore is a total lost cause.) But when Charlie learns that she's under the Fellowship's protection herself, well, "stressed" is an understatement. Ellauria should be the safest place for Charlie while the Fellowship works to find her family, but things in the mystical realm aren’t what they seem. Magic is failing, creatures are dying, and the Fellowship insists Charlie holds the key to saving everyone. With her family still missing and the danger in Ellauria growing, Charlie doesn't know who she can trust. She's dealing with a power she never asked for, falling for a guy she can't have, and being forced to choose between her destiny and her heart. And if she chooses wrong, she could destroy magic forever. Charlie may be in over her head
