Wings by Aprilynne Pike

Plot: "Fifteen-year-old Laurel has led a sheltered, homeschooled life in a very small town, so when her parents decide to move and enroll her in high school, she has trouble getting used to her new life. A life, as it turns out, that’s not at all like those of other kids. One clear sign is a winglike blossom that blooms on her back. Oh, and her new best friend, the scientifically minded David, reveals under a microscope that her cells are more plant than animal. But it takes an encounter at her old home with the handsome but decidedly different Tamani to convince her that she is a faerie. She also learns it’s up to her to save her land from the evil influences that are trying to take it away from her and her family. This first novel is clearly designed to attract the Twilight set, though there’s significantly less edge (and blood). There is, however, a familiar triangle. Will Laurel choose solid, steady David, or will she be unable to resist Tamani’s lure? Stay tuned. Fine escapist fare, this neatly mixes the everyday with the otherworldly"-Amazon's description
Review: I love Tamani. David is a nice guy too, but there's just something about Tamani that draws me in. I really, really liked this one. It started kinda slow for me at first, but once Tamani came into the picture I just couldn't put it down. You got to check this one out.
