Rollrock is an isolated, windswept island; a wild and salty landscape where fishermen and their families must wring a living from the stormy seas. But Rollrock is also a place of eerie magic, and of powerful desire. Down on the beach, the outcast witch of Rollrock casts her spells, and draws mysterious girls from the sea.

These are girls with long, pale limbs and faces of haunting innocence – the most enchantingly beautiful creatures the fishermen of Rollrock have ever seen. The island is envied, and many a man is lured to Rollrock with the promise of a sea wife. But the arrival of these women is the ruin of countless families – and to the despair of the men of Rollrock, magic always has its price.

The brides do not belong on land. One day, the sea will claim them back.
