Spending the summer at her grandmother's house is the last thing Sarah wants to do-especially now that Grandma Winnie has died-but she has no choice. Her parents have to fix the place up before they can sell it, and Sarah and her brother, Billy, have to help. But the tedious work turns into a thrilling mystery when Sarah discovers an unfinished letter her grandmother wrote: Strange things are happening behind the bookcase...
As Sarah investigates, she finds a doorway into Scotopia, the land where shadows come from. And with a talking cat named Balthazat as her guide, Sarah begins an unforgettable adventure into a world filled with countless dangers. Who can she trust? And can she face her fears, not only in Scotopia, but also back at Grandma Winnie's house, where more secrets and strange goings-on await her?
