A devout mermaid. A disgraced princess. A feud as ancient as the gods.

Worlds collide when Tallora is kidnapped from her ocean home and forced to be a pet to a tyrannical foreign empire. Her only hope for rescue lies with a sworn enemy—Princess Dauriel, infamous for her stone heart and conflicted past.

But when Dauriel’s kingdom comes to the cusp of war, could their uneasy alliance be the key to defeating a common foe? Or will their tenuous feelings lead them to ruin?

From the world of Fallen Gods comes a tale of ancient magic and cutthroat politics—and finding redemption through love.
