Divided (The Guardians #2)
by M.J. Stevens
The MECH power has been reawakened. They have driven the Guardians from their home, taken their powers and Selestia has been plunged into darkness. Trapped on an uncharted island, Mellea watches her home being torn apart by the MECH's leader, Doctor. An unlikely ally creates a serum to restore the Guardians to power. Mellea must fight the clock to find them. But what good is a key without a lock?
