Upon Cursed Tides. Tides of Maldon, #1

The deep doesn't forget. And it doesn't forgive. As a Warden of the Abyssal Watch, Nerida Maldon was trained to hunt corrupted creatures and guard the sea's boundaries. She wasn't trained to become its last hope. When void-tainted currents begin spreading through the deep, Nerida and her brothers are sent to find the source. What they uncover is older than history, and bound by magic that should've stayed buried.
Nerida survives. The sea isn't done with her. Taken by a cursed crew aboard a dying ship, she faces an impossible choice: walk away and let dozens fade into nothing, or awaken the legacy stirring inside her. As dark forces rise beneath the waves, Nerida must decide how far she's willing to go to stop what should never have surfaced.
