Quantum Coin took a good 100 pages or so to build up steam. Following up a fairly well wrapped up story makes it hard for a sequel to find it's own ground. Quantum Coin manages that and more with a really unique sci-fi premise and some mind bending twists. Myers moves away from the first books weakness which was in it's characters but still gets caught in that trap in the end. All in all a good book but not as gripping as it could be.
