In a world where every tapestry is a portal to somewhere else, a young woman must weave a long-forgotten masterpiece to unravel the mysterious death of one of Britain's greatest tapestry designers.

After spending her childhood working in her mother's repair shop, Sophie O'Toole is ready to shed her life in Western New York to study weaving at one of England's most prestigious colleges. At East Lawn, she will learn the secrets of transforming thread into the tapestries everyone uses for transportation and recreation.

But those aren't the only secrets in store for Sophie, whose roommate is the daughter of Britain's most beloved tapestry designer, the late Sabrina Maxwell. On a trip to the Maxwell family estate, Sophie becomes entangled with her roommate's brooding older brother, Holden, who is determined to solve the mystery behind his mother's murder.

When Sophie discovers the design for Sabrina's final, unwoven tapestry, it could be the clue that's been missing all this time. And Sophie is the only one Holden trusts to weave Sabrina's design. But will the tapestry unravel the mystery behind Sabrina's death? Or will the months of work - and the relationships Sophie sacrifices in the process - be in vain?
