Sandy and Dennys have always been the normal within their eccentric and extraordinary family, but one day, these twin brothers accidently intrude on one of their father’s science experiments and are taken to a remote point of time and space. In this strange desert-like place, they find themselves living among angelic beings, dwarf mammoths, and unicorns. The twins will be drawn into a fierce struggle between good and evil, and to control their families’ destiny. Madeleine L’Engle once again creates a dazzling adventure in this fourth instalments of the Wrinkle in Time Quintet in which science, mythology, fantasy, and reality inextricably combine to break down the barriers of imagination.
