The Tail of Summer

Sophia is an east coast mermaid with a light pink tail that sparkles in sunlight or moonlight. She is casted out on a quest, summoned by her necklace, to complete her destiny. Sophia has three days to prove herself worthy of keeping the siren's gift by saving a human's life. She has to travel on land for the first time and meet love?

Ryan is the typical geek at school who never gets people to notice him, especially girls.

Daniel is the first to make a big impression on Sophia and thinks that her heart will be his to keep.

Both are teenage brothers with the same love interest.

Then, there are some problems with jealousy, siren magic, and the difference between humans and mermaids.
