The Hills Are Shadows

It was supposed to be a homecoming and reunion, but when Anne Tennyson Miller (Tenn to her friends and family) returns to Driftwood Bay with her new friend Una, they find a ghost town.
Something has gone terribly wrong in the world. The sea is rising fast, and everyone — almost everyone — has fled to the hills. Danger and treachery lurk on a highway littered with abandoned cars and possessions, and the girls, along with two young strangers who conceal a mystery of their own, head across country. They climb through the wilderness in hopes of finding the Miller family and safety, perhaps, from the relentless tide. But their adventures have only begun . . .
