This fantasy for middle grade readers weaves together three stories of time travel, magical realism and environmental consciousness. In 1910, Elliott Hansinger, a brilliant but eccentric engineer, builds a machine that accidentally transports his wife and his children, Ben and Lizzy, into another dimension of fluctuating times and realities. In the summer of 2021, Annie and Will Hartley are precocious youngsters who inadvertently enter a time portal that sends them 100 years into the past. There they encounter Elliott and his family and discover that they are all trapped in a mysterious world of animals and nature ruled by a wolf-beast, a crafty creature who uses magic to manipulate the flow and direction of time and protect the sacred space of his mountain domain.
