Magic Times Three

Could the past be altered? Would crushing a single insect during a Jurassic trek ripple outward and rewrite the course of human events? This novel asks whether the demons of another realm could play a part in such changes. Its plot braids together a romance between a human and a demon, parallel universes, a woman working as a spy, and journeys through time.

The book is part of the Magic by the Numbers series by Lyndon Hardy, whose fantasy stories are known for explaining the workings of magic in a systematic, logical way.
