Lightmare

Fiora’s world has been turned upside down in this second book in the exciting upper middle grade fantasy series The Incorruptibles, for fans of Keeper of the Lost Cities and The Marvellers.

Still reeling from recent tragedies, Fiora and her Thistle teammates are on the run and living in seclusion. Times are difficult, and the Thistles are more vulnerable to the sorcerer threat than ever. But all is not lost. The Thistles are forming a plan to fight back. But when terrible truths are revealed, deep fractures form within the team. When one of their own makes a choice Fiora never saw coming—and cannot possibly understand—Fiora and her friends are forced to reexamine what is good and what is evil…as well as the gray space between.
