  • The grand finale to the loosely-connected Psi Powers series of novels, Aaronovitch's computer suffered a hard drive failure resulting in the loss of his work on the novel apart from the outline and a few scenes. Originally intended for publication in November 1996, the book's appearance was delayed six months as author Kate Orman was called in to finish writing the novel.
