I must say I was very excited to read Fusion Fire after having read the 1988 version of Firebird. I was aware that Firebird was redone and that its sequals were writen to follow the new format aswell, but I was unprepared for the differences in the book. I had been warned that Tyres preaches, and that this book is better left to those who wish to read such, but as one who respects but does not choose to folow that doctrine, I found that at times I felt alienated or better yet, uncomfortable. Getting past that, the book is a good science fiction read that presents moral dilemas and philosophical problems that can, if you don't technically follow the christian doctrine, make one ponder human nature and cultural formation. The reason I say this book should be taken in parts is that the characters are placed in terrible emotional situations that either don't end till a disappointing few pages before the end, or do end only to begin another, even worse dilema, ten pages away.
