Ten-year-old Mary Lennox arrives at a secluded estate on the Yorkshire moors with a scowl and a chip on her shoulder. First, there's Martha Sowerby: the too-cheery maid with bothersome questions who seems out of place in the dreary manor. Then there's the elusive Uncle Craven, Mary's only remaining family-whom she's not permitted to see. And finally, there are the mysteries that seem to haunt the run-down place: rumors of a lost garden with a tragic past, and a midnight wail that echoes across the moors at night. As Mary begins to explore this new world alongside her ragtag companions - a cocky robin redbreast, a sour-faced gardener, and a boy who can talk to animals - she learns that even the loneliest of hearts can grow roots in rocky soil.
