Publisher's Synopsis
This eighth sequel to The Book in the Loft series begins with a long and boring trip to the planet Surion, but before reaching their objective, the sudden appearance of a mystery ship throws the crew of the Circle of Planets' starship Explorer into a conflict with those from two warring worlds. Deadly results follow, resulting in the ship's helmsman coming face-to-face with the grandfather of all time paradoxes. Neil MacBruce and Captain Jon Varkon are then faced with finding the solutions to prevent the paradox from causing timeline changes, not only for everyone on Explorer, but for everyone residing within the Circle of Planets star system.
