Under the Sea

Wow.  I was blown away by Ingo by Helen Dunmore. 
What a lovely book!
Although she writes for kids, she doesn't patronize, resulting in a story that is very deep and beautifully written.

Sapphire and her brother Conor live by the sea.  Their father goes missing at sea one day and they just can't believe that he is dead.  They soon find out that their cove is magical, that strange creatures lurk beneath the waves and can take them down into the depths of the ocean also. 
Sapphire has to deal with her desires to stay in Ingo (the world beneath the air) and returning to those she loves.

As someone who lost their dad as a child, I loved the way the author dealt with the feelings that the children had to go through with the loss of their dad and their mother's dating.  Dunmore's love of the sea is so obvious it makes you feel as though you are submerged also.
I can't wait to read the next in this series!
