Seven years has passed since Jenny's brother, Tom, was swallowed whole by the trees. Gone but not forgotten, Jenny returns to the forest for a final closure. The forest calls out to her, with the sound of a flute, his music, and the sound pulls her deep into the forest and she soon finds herself in a place where all is not what it seems. The World of the Faerie Realm. 
 She meets Jack, the Guardian of the Edge, a mysterious and handsome boy who promises to help her find Tom. Along with Puck, Robin Goodfellow, they must embark on a dangerous journey to save her brother without losing themselves in the process. 
 The story is magical, enchanting and beautiful written. The cover is beautiful. The Treachery of Beautiful Things shows you just how treacherous beautiful things can be!
