"A hundred miles from the mainland, half in the sea, half out of it.
The rules are different here..."

All 13-year-old Blair Zielinski wants is a way off the remote Scottish island her parents have dragged her to. Roscoe is home to thousands of deer, a couple of hundred people, a complete lack of phone signal, and some unusual violet-eyed creatures.

Blair is miserable, until an otherworldly woman with antlers, one of the island's darkly magical fey folk, offers her an irresistible deal: complete three tasks and Blair's wish will be granted.

As she unravels the island's secrets, Blair soon discovers that a fey bargain cannot be broken, and her wish has put everyone on Roscoe at risk. Can Blair find a way to save her family, and the place at the edge of the silver sea that she has come to call home?

From the author of The Sky Beneath the Stone, this wildly magical upper middle-grade fantasy explores family and friendship, the balance between humans and nature, and the people and places we embrace as our own. The Edge of the Silver Sea deftly weaves Celtic mythology and folklore -- from kelpies and selkies, to will-o'-the-wisps and river spirits -- with themes of environmentalism, in Alex Mullarky's trademark captivating style.
