"You'll find the mermaid of Zennor inside Zennor Church, if you know where to look." This is the first sentence in Ingo, the first book to start off this fantasy quartet about a world buried deep under the waves. Sapphire doesn't believe her father is dead when one night, he suddenly disappears into the ocean. This starts a chain of events that lead Sapphy and her brother, Connor to discover something they only believed to be real in fairy tales, Mer people. Sapphy and Connor feel as if their new Mer friends know something about their father's disappearence, but why won't they tell them.
I liked this book for its detail. I was green with envy as Helen Dunmore described how free Sapphy felt in the water and I wished that I could swim in the cool waters as well. I've also read the second book, Tide Knot, and it is just as good as the first one.
I recomend this book for readers age nine and up. There's hardly any swearing, romance, or violence and it's a book of fantasy for younger readers.
