Wow... a lot of people picked "The Darkest Hour". I personally enjoyed Forest of Secrets the best, that book is where I think a lot of the plot started to develop and get more interesting. I thought it was better than the first two, even though I still love the first two.
Anyway, I think Firestar is the leader who I like best considering Bluestar went a bit crazy...
please comment and post suggestions thanks a lot :)
