(Rua, Book 2) Celeste is not your ordinary teenage girl. She's part of a hidden world. Something is after her kind. Only she can stop it. Celeste is new to the hidden world of the Tuatha and Sidhe, a people only thought to exist in Celtic mythology. With her adoptive family and boyfriend Rylan by her side, she travels to Ireland to meet her fellow Tuatha. Her happy orientation is shattered with a brutal murder and ensuing chaos in the Sidhe world. Rifts form with her loved ones as she copes with her rapidly increasing powers and shifting position. In the midst of the upheaval, Celeste and her friends must discover who seeks to destroy the Tuatha and open the seam between the human and Sidhe world with deadly consequences.
