The biggest problem I have with this book is the ending. Correction: The biggest problem I have with this book is the collection of alternate endings. There are a few points in the book where Weiss tells one version of an event and then goes back in the following chapter and describes how the event actually happened. The book ends with a series of these alternate variations that make it difficult to really see how the story was supposed to have turned out.
Additionally, there are some technical errors here and there. The one that really affects the plot is the suggestion that the reason Pennyman can't play Lucky Wander Boy on an emulator is that someone would have to build a whole new CPU emulator for what appears to simply be a Z80 with a slightly higher clock speed than the Z80H.
