Lost Book... I have been searching for a book now for a few years. I read I when I was about 10 or 11, so about 12 years ago.it's all a bit vague, but basically it was about a girl who moved to the sea. She didn't know her mum but she found out her mum was a mermaid. The book had horses that ran from the waves and sirens that lured sailors. I would love to read it again, of only I knew the name!!
