If you haven’t read the previous four novels in the Hamish McAllister Chronicles, or even if you have, and you don’t want any clues as to what happens in the fifth novel, don’t read any further….


The virtual world is running out of computing resources, and its chief software architect, Rajesh Singh, is desperate.

When Japanese psychologist, Hisako Myamoto, proposes to use her AltLife research project to demonstrate how quantum computers could solve their problem, Hamish and Raj jump at her offer.

But Hisako has a darker reason for wanting to use the virtual world’s unique software facilities: a second secret project that neither Hamish nor Raj can ever know about.
