Life flourishes in the Book, a realm of stacked worlds, like the pages of a novel. Each more unique than the last. Those who can travel through them are page turners. Blessed with the power to go from one page to the next. For investigator Fiona Thorne, being a turner is normal life. Solving mysteries is where the excitement lives. Minor cases are still work to be done, people to be helped, and she's determined to make an impact in the Book, no matter what. Blaze, the page of fire, is wasting away. Fire elementals are being smuggled out in waves, but by whom? Fiona is on the job and nothing will hold her back, not even the overbearing Travel Guild. They may run the Book, but they don't rule her. With the fire page and its creatures on the brink of winking out, she has to race to unravel who the smugglers are and how to stop them. Is there more to this case than it seems? Can Fiona read between the lines and solve it in time?
