The fourth in the Time Quartet series, this book focuses on Sandy and Dennys, the twins of the Murray family featured in such books as A Wrinkle in Time and A Wind in the Door . Life for the twins is relatively run-of-the-mill until the day they discover the new computer in their parents` laboratory. When they type in Take me someplace warm...someplace warm and sparsely populated, they find themselves traveling across time and space to a harsh and mysterious desert. Copyright (C) Muze Inc. 2005.
