The Rising of water has created a new world order for humans.  Most of the earth is now covered by oceans.  Whole townships live within floating structures.  Humans have even adapted to be able to live entirely subsea.  Yet economic commerce retreated to basic supply and demand.  These forces combine to give Ty and Gemma a mission they never want to go on again.

Ty’s Dark Gift of sonar will help them overcome human and animal attacks, but will is be enough to locate his kidnapped Ma and Pa?  Mind games make for another level of mystery in this fast-paced middle level novel.  There is a deepening fondness growing between Ty and Gemma but everything is totally appropriate for its intended audience.  Kat Falls very creative dystopian story is full of imaginative details that should impress all readers.  In Ty, she has made a compassionate, charismatic role model for boys and girls.
