The nation of Outer Melvia runs on the power of dragon oil, but only the Hunters of Map's End are fearless-or foolish-enough to pursue the great beasts of the deep.

In the wake of a broken engagement, Ilsa Starling boards the Hunting vessel Relentless in search of the solace the sea promises her.

But dragons are not the only threats that lurk in these uncharted waters. As first mate aboard Relentless, Ilsa becomes a key player in the impossible quest determined by her captain, Adam Chase. Once Map's End's rising star, Chase lost everything to an ill-fated encounter with a legendary white dragon that haunts the seas at the very edge of the world. Now the captain swears to avenge himself on the beast and restore all that was stolen from him, no matter what-or who-he may lose along the way.

In this gaslamp fantasy reimagining of Moby Dick, Hannah Kaye spins a tale of hurt and healing, breathing hope into Herman Melville's timeless tragedy.
