Not my typical book at all, but dang if it didn’t keep me hooked. The story moves at a brisk pace that keeps you going, and I gasped and exclaimed aloud multiple times. The physics aspect was believable but also accessible, and the characters were great. Also loved the depictions of both good and evil in all the cultures represented, no archetypal banality here. And MAJOR bonus, especially for this genre—NO SWEARING. Looking forward to reading his other works, and the sequel (coming soon) to The Lost Notebook!
