"The Kings of Clonmel" is the 8th book in the Ranger's Apprentice Series. This is a great series, written by Australian author John Flanagan. Flanagan originally began writing it to give his son something to read, and it's grown into this wonderful series.
In "The Kings of Clonmel" our ranger hero Will has just gotten a life altering new assignment serving the Kingdom of Araluen, and one that he is very happy about. Soon though, his mentor Halt returns from neighboring Clonmel with news of a cult destabilizing that country. So, to protect Araluen's interests, Halt, Will and Horace head off to Clonmel to see what they can do to stop this cult. Along their journey, there is plenty of humorous banter between the 3 heroes, and you get to see just how much Will and Horace have grown over these 8 books.
This is another solid book in this series. It's not as action packed as prior books, but I think that's ok. "The Kings of Clonmel" is actually part of a 2 book series. The next book, "Halt's Peril" will be released in the US this fall. It has already been released on Australia. And, a 10th book is planned for a November Australian release. Flanagan shows no sign of slowing down with writing these books, and I think that is a very good thing. I hope you give this series a try, I don't think you'll regret it.
