Book 2 of the Quantum Evolution series is an even bigger brain burner than the first one so don't pick this up unless your mind is in the right place. In The Quantum Magician, Belisarius pulled off the biggest con of his career and also walked away with the Time Gates, which could be the most valuable asset in the universe. He is back with Cassandra, the love of his life, and he has also possibly reached a new state of evolution for his sub-species, the Homo Quantus. He has managed to find a way to see the quantum possibilities of the universe without having to enter a fugue state, so things are looking pretty good for him. However, as he approaches the Garret, the home world of his people that he left long ago, he watches it get destroyed before his very eyes.
