During a Florida vacation CPR class, eleven-year-old Maxzyne's curiosity catapults her into an underwater world of naiads, nixies, and other lagoon creatures fighting to prevent the draining of beautiful Liliana Springs.

Will Sereia, the vain water hag in cahoots with greedy Westbrook water-bottling company, prevail in her evil plan?

Maxzyne must work with an overbearing Eagle Scout classmate, Oliver, in a battle that tests the wits and will of two very unlikely partners. Can they survive each other and this dangerous aquamarine sphere that needs their help to exist?
