From the internationally bestselling author of The Dressmaker comes a riveting new novel about a young archaeologist who unearths ancient secrets, a tragic romance, and Viking treasure on a remote Scottish island.

In 2011 Freya Dane, a Ph.D. candidate in archaeology, arrives on the ancient Scottish island of Findnar. After years of estrangement from her father, himself an archaeologist who recently died, Freya has come to find out what she can about his work. As she reads through his research notes, she sees he learned a great deal about the Viking and Christian history of the island. But what he found only scratches the surface of the discoveries Freya is about to make.

In 800 A.D. a Pictish girl named Signy loses her entire family during a Viking raid. She is taken in by the surviving members of the Christian community on Findnar, but when she falls deeply in love with a Viking boy, she is cast out. She eventually becomes a nun and finds herself at the center of the clash between the island's three religious cultures. The tragedy of her story is that, in the end, she must choose among her adopted faith, her native religion, and the man she loves.

Centuries apart, Freya and Signy are each on the verge of life-changing events that will bring present-day and Viking-era Scotland together. The Island House plunges the reader into a past that never dies and a love that reaches out across a thousand years.
