I was already familiar with Debra Castaneda via The Root Witch, which I thought was a really cool and unique story. I enjoyed it a lot. This book, however, blew me away. Nature and the ocean are already scary as hell, so add a big storm and something from the deep and I'm all in. It is deeply unsettling and fraught with tension - it gave me a bit of real-world anxiety which is pretty rare. 5 stars
