She never believed in love. Especially not with an alien. Until he risked everything to save her. Dive instructor Maelis has always trusted the ocean-but not the strange green-skinned alien warriors sent to Earth to find their fated mates. Keeping her distance was easy... until a violent storm traps her underwater, and only one person risks his life to save her. Cerban knows Maelis is his mate the moment he sees her. But human rules forbid contact, and breaking them could mean exile-or worse. When a mysterious cave reveals ancient finfolk secrets buried beneath the island, Cerban and Maelis must work together to uncover the truth... and fight for a future that defies every rule. Drawn together by danger, desire, and something far deeper, they'll face storms above and below the sea. But when Cerban's forbidden love threatens his place on Earth, Maelis must decide: trust her head, or follow her heart? Perfect for fans of alien soulmate romance, forbidden love, protective alien heroes, fated mates, forced proximity, and ocean-set sci-fi adventures, Cerban is a standalone romance in the steamy Starlight Mermen series. Part of the Intergalactic Dating Agency.
