The grass grew taller than the house itself, surrounding it on all sides. It stuffed the keyholes and scraped against the roof. It shook the walls and made paintings shiver. Seven years ago, the Ballastian sisters’ parents left them in the magical Straygarden Place, a house surrounded by tall silver grass and floating trees, with a warning not to leave and venture into the grass around the house.

But when Winnow does the unthinkable and goes into the grass, everything twelve-year-old Mayhap thought she knew about her home, her family, and even herself starts to unravel.
