Wild Dark Shore by Charlotte McConaghy

Off the coast of Antarctica lies an island where a community of scientists had once gathered to oversee a seed bank. Rising oceans cause the project to sunset and only the Salt family remains on the island. After a violent storm washes a woman ashore, secrets slowly come to light in this fantastic mystery novel.
