Delivery time: 8-12 business days (International)
Fourteenyearold Abbey Sinclair likes to spend her afternoons in the physics lab learning about momentum and gravitational pull. But her practical scientific mind is put to the test when her older brother, Simon, discovers a mysterious path of stones that allows them, along with Abbeys twin, Caleb, to travel back and forth between their world and what appears to be...the future. Unfortunately, theyre not the only ones who know about the stones, and they soon realize their lives are in danger from a man known only as Mantis. Abbey, Caleb, and Simon must follow a twisting trail of clues that will lead them from their autistic neighbor, Mark, to a strange professor who claims to know the rules of the stones, and to multiple futuressome of whose inhabitants dont want to stay put. It will take all of Abbeys analytical skills to unravel the secrets of the stones, uncover the threads that tie the futures together, thwart Mantiss plan, and, most importantly, keep her family alivenow and in the future. A Pair of Docks explores Einsteins Theory of Relativity, the meaning of time, the potential for parallel universes, and the boundary between science and witchcraft. It is the first novel in the Derivatives of Displacement series.
