When I read this book for the first time, I literaly could not put it down. Since then I have read it and the rest of the series many times over, and this book never loses it's flavor. The discriptions and characters were so vivid that I could see everything that was happening, and it felt almost as if I was there. Anyway, in this book, Luke decides Jacen, Jaina, Tenel Ka, and Lowie are now ready to build their lightsabers. The story goes into great but not tedious details as to how lightsabers work, which is something I have always wondered about. So anyway, Jacen, Jaina, and Lowie all build their lightsabers slowly and carefully like they are supposed to, but Tenel Ka rushes through hers so she can be the first one to finish, and then when she and Jacen spar, something terrible happens.... Part of why I loved this book in particular was that it had a lot of character development without compromising action, most especially in Tenel Ka who is the main focus of this story. I greatly enjoyed this, because Tenel Ka is definitly my favorite character in the series, because she is so strong and tough and doesn't let anything stop her, not even a crippling accident, and of course because she is a warrior princess. This book would be best if read after the previous three books in the series, though it can be understood on it's own too. The reading level of this series is not very high, just high enough to be above the 9-12 age range. Any Star Wars fan over the age of ten would probably like this book.
