If you loved Forgive My Fins by Tera Lynn Childs
Readers who love Forgive My Fins tend to enjoy its light, funny voice and its mix of everyday teen worries with a secret magical world. Lily's crush, her mermaid family, and her awkward human life give the story a playful tone, and the pace moves quickly through misunderstandings and small disasters. It is romantic without being heavy, and it treats a first love as a big, serious deal. If you want more of that blend of humour, sea magic and high-school romance, these picks are a good place to start.
