A Quill Ladder

Derivatives of Displacement, #2

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.
