Blue Water (A Little Mermaid Reverse Fairytale Book 2)
by J. A. Armitage
Princess Erica can't live under the ocean and Ari can't live above it and yet they are destined to be together, bonded by magic. With circumstances keeping them apart and magic bringing them together, they find themselves living impossible lives with no way around it. Snatching time together here and there is one thing, but when Erica's father becomes ill and with Erica due to ascend to the throne, even that has to stop.
