''Sea of Whispers'' has a mystery to solve, a dangerous adventure to experience vicariously, a strong and engaging central character, some fantastic dialogue, a vivid naturalistic setting, an edge of the supernatural, and relevant themes of difference and prejudice. Honestly. If there's more you want, I'll despair of you. Highly recommended.
We also have a review of [[Night Runner by Tim Bowler]].
Another wonderful, wonderful book involving a remote community living with the power of the sea is Margo Lanagan's selkie story, [[The Brides of Rollrock Island by Margo Lanagan|The Brides of Rollrock Island]].
