When Phoebe Rothschild meets weird Mallory Tolliver in 7th grade, it's the beginning of a fast and true friendship--but, it turns out, Mallory isn't what she seems. In their junior year of high school, Mallory's beautiful and shady brother Ryland shows up and it isn't a secret to the reader that both Mallory and Ryland are denizens of the world of faerie who are luring Phoebe to her doom because of a pact Phoebe's ancestor made with the faery queen. This isn't the story of a romance, however, but of a friendship, and it is suspenseful and heartbreaking, as Phoebe learns she herself is far from ordinary.
