Beneath a Sapphire Sea (Merfolk Trilogy #3)

Beneath the shimmering, sunlit surface of the ocean there lives a race of rare and wondrous men and women. They have walked upon the land, but their true heritage is as beings of the sea. Now their people face a grave peril. And one woman holds the key to their survival...

SHE WAS A SULTRY SIREN WITH AN UNDISCOVERED HERITAGE
A scholar of sea lore, Meredith had come to the Greek island to follow her academic pursuits. But in one magical meeting she gazed into the mesmerizing blue eyes of a proud, determined warrior of the sea...and was eternally linked with a world far more elusive and mysteriously seductive than her own. For she alone possessed a scroll that held the secrets of his people. She alone was their only hope. And she alone would surrender to the powers of a love destined by the tides.

HE WAS AN AZURE-EYED WARRIOR OF A LONG-FORGOTTEN RACE
With eyes that told the stories of eternity, Galen lured this exquisite woman to join him in a battle for power beneath the sea. For now Galen's clan faces two enemies: Anastas, who wars against his own people, and a deadly unseen foe. He will cross into Meredith's world to choose her as a bold warrior for his people--and as his only love. He will share with her the secrets of a realm beyond time and imagining, and together they will emerge victorious as the keepers of its fate...or see its fragile beauty destroyed forever.
