Darkest Tides. Tides of Maldon, #3

Some things were buried for a reason. And some wars never really ended. When a long-lost structure rises from the deep, the Abyssal Watch expects danger. They don't expect a prison - or the goddess trapped inside. Mikael Maldon breaks the seal. He frees Aurelyne, a fallen deity bound by ancient magic and betrayed by her sister. The moment he does, the ocean begins to change. Corruption spreads. Creatures stir.
And the Watch faces a threat they can't contain - a divine war spilling into mortal waters. As loyalties fracture and the tide darkens, Mikael must choose between the duty he swore to uphold. and the goddess who could tear it all apart.
