Why I chose this book 
 I wanted to read some classic fantasy this year, and several of my friends said they enjoyed this one. 
 Rating/content 
 I give this book 4 out of 5 stars. 
 This book is not exactly young adult, but the main protagonist is a teenage girl. She reluctantly takes over the mission of a Green Rider (messenger to the king), and the first half of the book follows a fairly traditional fantasy quest progression. The second half of the book is basically about overcoming the bad guy's plans to take over the kingdom. This is a pretty clean read, with only the usual amount of fantasy violence-sword fights, magical fights, and fighting monsters. 
 Good points 
 This was a great read. Karigan is the typical reluctant heroine who is dragged into a mission that she doesn't really want to go on. The plot progresses at a good pace, although as is typical in quest fantasies, there are digressions to meet mentors and overcome difficulties, not to mention avoiding the bad guys as they chase her. All the incidents that happen to Karigan, however, do further the plot or foreshadow events that happen later. 
 The cast of characters is interesting, from the slightly bizarre old lady mentors to the evil Grey One, to the king and his brother who fight for the throne. 
 I like the thread relating to the game of Intrigue. It's a made-up board game, a little like chess, and it features at several times in the book, and has its own little arc. 
 The concept of the Green Riders is interesting, too: effectively, an elite band of trained messengers who cannot resist the call of the open road and risk their lives to deliver messages for king and country. 
 I also enjoyed the magic system in this book. At times, it's only hinted at, but the magic of the Grey One contrasts with the magic of the Green Riders, as Karigan begins to come to terms with her destiny. 
 Bad points 
 I couldn't really put my finger on one particular bad thing in this book, however, it was a bit predictable. Nothing surprised me. The mentors turn out to be lovely old ladies, when I was wondering at the back of my mind if they had ulterior motives. Karigan faces detours and set backs, but the plot progressses as you would expect: she beats the monsters, and fights the bad guys etc. She appears to be set against being a Green Rider but you know blatantly that she is going to become one (although it didn't happen at the end of this book), but it was a case of she protests too much. 
 Oh, and I thought the implied attraction between her and the king was a tad icky, given her young age. But that plot line didn't really go anywhere, thankfully. 
 Overall 
 I'd recommend this as a good solid enjoyable fantasy read, but don't expect any major surprises!
