Ava McCoy has always been drawn to the ocean, but when a shocking memory resurfaces, the ocean is suddenly her answer. For years, Ava was blissfully unaware of the Mer world, but suddenly, she remembers Daniel and everything changes.

Daniel is a Mer-Male and any knowledge of his world is forbidden for the humans of Tamuto. And now that Ava knows him, she can’t stay away and pretend their connection isn’t real. But Ava isn’t the only one who knows the Mer secret, and when it gets out that Ava and Daniel have been secretly meeting, Daniel is imprisoned.

Daniel’s only hope is Ava, and she vows to do whatever it takes to save him, no matter the cost. Together, they must beat the odds and make sure they aren’t separated again—this time, for good.
