Magic Tree House
Junie B. Jones
After her Grandma Winnie's death, Sarah finds herself forced to spend the summer at the old woman's house while her parents attempt to fix the place up enough to sell it. But, for Sarah, her summer doesn't really begin until after she finds an unfinished letter from her grandmother that warns, Strange things are happening behind the bookcase. Soon Sarah steps through a doorway into Scotopia, the land where shadows come from. There, she confronts a thrilling world of danger--but the real fears she'll need to face are the ones she left behind, at home.
