In the little town of Blackbird Tree a series of curious events unfold when Naomi and Lizzie, two spirited orphan girls, meet the strangely charming new boy, Finn. Three locked trunks, the mysterious Dingle Dangle man, a pair of rooks, a crooked bridge, and that boy change their lives for ever. As the story alternates between their small town and across-the-ocean Ireland, two worlds are woven together, revealing that hearts can be mended and that there is indeed a gossamer thread that connects us all.
