Some witches cast spells. Others sacrifice everything. A Sister forced to do the unthinkable. A kingdom on the brink. A quartet of witches intent on altering History. For centuries, Sister Winter’s life has been dictated by a Grimoire—the Book her Sister Autumn just destroyed. Despite the necessity of its destruction to end a vile shadow organization and the Sisters’ three hundred years of separation, Wendolyn is left adrift without its guidance. As secrets from long ago begin to rise up around her, Sister Winter must face what haunts her, while the Prince of Mereville uses his abilities as Marchand de Mort to infiltrate The Order—the shadow regime that wants him dead. Will the ghosts of the past keep Wendolyn from her Sisters? Will their differences spell the end for Midlerea? Or can they put aside what’s been to save the dark prince and the future of the realm?
