Dominic Salt and his three children live on a remote island off the coast of Antarctica, called Shearwater. The island is home to the world's largest seed bank. The waters are rising and soon the island will be uninhabitable. All of the other researchers have already left and the Salt family will only be there a few more weeks finishing up saving and sorting the seeds. After a huge storm, a mysterious woman washes up on the shore, barely alive. They take her in and help nurse her back to health. As we go on, we learn that all is not what it seems and that both Dominic and the woman, Rowan have secrets to hide. As Rowan keeps growing closer to the family she slowly starts to uncover some things. They must decide whether to put aside their differences to work together to save the seeds and themselves. There are lots of twists and turns in this atmospheric story. The island is so well described and definitely becomes a character itself. As the tension continues to mount, you feel like you are trapped on the island with them. The writing is really beautiful and keeps you right in it until the end.

The multicast narration was excellent and really added to the atmosphere of the story. I thought it was maybe a bit long, but overall a great read!
