When a quantum supercomputer's "reality simulator" program causes temporary insanity in its beta-testers, Lee Green rolls up his sleeves and dives into a virtual world to debug the problem. Only he discovers that place is more real than anyone imagined. He finds alternate versions of his friends in that mad science reality, their lives and relationships very different from those in the "real" world. Quantum entanglements become romantic entanglements as he meets his love again in each new dimension. Lee must save these other lives, decide which destiny is truly his, and what he's willing to sacrifice to get there.
