Jennifer Ellis’ Derivatives of Displacement is an ideal series for tweens who love mystery, fantasy as magic, but are also fascinated by science, nature and cutting-edge theories of physics like parallel universes and time travel.
The first two books in the series are very highly-rated and the third is set for release this week. Better yet, all three are currently bargain-priced!
Fourteen-year-old 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 Abbey’s twin, Caleb, to travel back and forth between their world and what appears to be…the future.
Unfortunately, they’re 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 neighbor with Asperger’s to a strange professor who claims to know the rules of the stones, and to multiple futures—some of whose inhabitants don’t want to stay put.
It will take all of Abbey’s analytical skills to unravel the secrets of the stones, uncover the threads that tie the futures together, thwart Mantis’s plan, and, most importantly, keep her family alive—now and in the future.
A Pair of Docks is an action-adventure for kids and adults that explores Einstein’s Theory of Relativity, parallel universes, time travel and the boundary between science and magic. It is the first novel in the Derivatives of Displacement series. Lovers of fantasy and science fiction will find plenty to like in A Pair of Docks.
Now that the witches have been rescued from Nowhere and Mantis no longer seems to be a threat to Simon, Abbey Sinclair just wants to return to her quiet life of chemistry experiments and physics textbooks. But life is anything but quiet for the Sinclairs. Abbey’s mother is taking secret trips to the stones with Caleb, Simon has been arrested for hacking into the City Hall computer, and to really complicate matters, the witches from Nowhere have moved in across the street.
Meanwhile, Mark has become increasingly obsessed with some old maps of Coventry, convinced that their strange markings hide an important secret. But when others—witches, of course—start to show an interest in these very same maps, Abbey, Mark, and Caleb find themselves on the run. Soon the race is on to see who can unravel the secrets of the maps first, and Abbey still doesn’t even know which witches are on the good side—if there is a good side.
Abbey’s parents are still missing, possibly trapped in a parallel universe, and the adults around her won’t give her any answers. So when she and Caleb once again travel to a possible future—one in which Coventry City is very much not as it should be—it’s up to them, and their neighbour Mark, to try to find her parents and set things right.
But it won’t be that easy. Abbey and Caleb become separated, the stones themselves seem to be breaking down, Mark encounters odd ghosts and his half-sister Sandy beneath the Granton Dam, Ian and Sylvain continue to lead them astray, and a powerful witch named Quinta is reshaping the futures to mysterious ends.
To save the future—or at least get everyone home—science-minded Abbey may have to perform magic. And to do so, she will have to believe…
