A friend of mine is also launching right now! Mariella Hunt has The Sea Rose and it's good! I read it on Kindle Vella, now she has expanded it and made it even better (didn't know she could make it better).
For centuries, the land-bound descendants of Merpeople have been confined to hidden districts where they will not disturb proper society. When Peter, Earl of Everly, flees his engagement ball, he finds himself stranded among the half-Mer. Will he encounter hostility from society’s outcasts, or could they be hiding something he’s always sought? Rejected by Lord Everly, Lady Meredith Bannister’s future is dark. Burdened with the secret of her heritage, can she embrace her identity before it is taken by force?
