She can save her world...but only by risking the life of the man she loves.

A deadly virus attacks the inhabitants of Zephyria. Princess Aquatania, a sea dragon shifter and sorceress, also a brilliant scientist and doctor, is determined to combat the contagion that swiftly afflicts most lifeforms.

Aquatania devises a daring plan, harnessing various strains of dragon blood in her quest for a cure for the population. To find it, she must journey into the crushing depths of the ocean.

At her side is Kieran, the formidable fire dragon general of the royal legions. As they plunge into a perilous quest beneath the waves, their contrasting powers-her command of the sea, his mastery of flame-become their greatest weapon...and the spark of an unbreakable bond.

With the virus spreading and enemies closing in from above and below, Aquatania and Kieran must race against time, trust in each other completely, and risk everything.
