This book is a novelization of the two-part episode "Gun On Ice Planet Zero" of the original series. That episode is one of the best episodes of the series, the special effects of the ice planet are superb and still wear well after thirty years. While this book is kept close to the original story, there are some areas where it is much weaker.
In the original story, Baltar is commanding the base ships and his interaction with the Cylon Lucifer was one of the best aspects of the episode. However, in this story, it is the Cylon Imperious Leader who commands the base ships. Furthermore, the Cylon leader interacts with a simulacrum of Starbuck, which is forced and a bit absurd. The section in the book where Boxey is in a Cylon fighter and Apollo flies another fighter above it so that Croft can use mountaineer equipment to jump from ship to ship and rescue Boxey by pulling him out is absurd. These are space ships designed for combat. The idea that someone could so easily access such a ship is nonsense. The book would have been much better if that section had been edited out.
One positive aspect of the book is the sections narrated by Croft. This is an opportunity to get inside the mind of the man and understand his actions. There are some statements concerning his past in the episode, but it is too limited to be helpful. Overall though, I found the book disappointing.
