When twelve-year-old Lise spends the summer on an island in Maine with her self-reliant mother and bright--but oddly mute--younger brother, her formerly safe world is complicated by an aged Indian neighbor, her mother's childhood friend, and a hurricane.

"Pat and Jen do everything together, including saving the day! But when Jen and Evil Jen find out they have one chance to find their long-lost mother in the Overworld, Jen is going to take it--even if it means that Pat can not join her on an adventure for the first time ever."--Jacket.
