    About The Library of Unruly Treasures

    The Borrowers meets Matilida in this funny, winning story of a girl who finds herself an unlikely hero when she stumbles upon a big secret about little creatures. The latest book from the National Book Award winning author of the Penderwicks series.

    Gwen MacKinnon’s parents are dreadful. Truly, deeply, almost impressively dreadful. So Gwen’s not upset at all when she’s foisted onto her never-before-seen Uncle Matthew for two weeks. Especially when it turns out he has a very opinionated dog named Pumpkin.

    Things take a turn for the weird when Gwen makes a discovery in the local library. A discovery that involves tiny creatures with wings.  And no, they’re not birds. They’re called Lanukan. But why can only Gwen and the youngest children, gathered for storytime, see them?

    The Ladhukan insist that Gwen is destined to help them find a new home. But how can a girl as unwanted, uncourageous, and generally unheroic as Gwen possibly come to the rescue? Pumpkin has a few ideas…
