Island of Legends (The Unwanteds), McMann Lisa

When hundreds of lights appear across the sea during Artim s first annual masquerade ball, the party is over. Artim is under attack, and Alex, the magical worlds young mage, must prove he can handle his newfound leadership.

Alex receives no help from Aaron, his scheming twin brother. Instead of rallying Quill to help defend their island, Aaron disappears and happens upon a dangerous secret hidden in the jungle--one with the potential to give him the power he desperately desires.

Even in the midst of battle Alex hasnt forgotten his promise to rescue his new friend Skys mother from the volatile Pirates Island, a rocky volcano that randomly spits fire and sinks beneath the oceans surface with little warning. Once the rescue team is on the way, friendships are tested and the stakes are high. Ultimately the team discovers there are more creatures than they ever imagined in the waters surrounding their island chain--and not all of them are friendly.
