A woman returns home and begins unraveling long-buried family secrets in this captivating novel of time travel, love, and legacy from the New York Times bestselling author of the Graceling Realm series.

In her mid-thirties, newly single and at loose ends, Matilda Frost has come home again. Settling back into a life she thought she’d outgrown, all she wants to do is hide from the world and devote her attention to building the miniature house she has been meticulously at work on.

Around her, things are largely the same. Her sister is still a force of nature. Her brother is still estranged, his whereabouts unknown. And her relationship with her best friend, Max, is still complicated; now back in each other’s orbit, old feelings might be resurfacing. But most familiar of all, her grandfather’s shadow still looms large over the house and the town. Decades ago, Grandfather Winthrop invented time-travel. His miraculous time-box stopped working when he died, and scientists have yet to figure out why.

When her beloved Uncle Ant disappears, Matilda realizes that in order to find him, she may need to dig into some of her grandfather's deepest-held secrets. But Grandfather Winthrop might not be the only family member with things to hide. . . .
