Chosen:
Nothing in particular at first made me choose this book. I was short on time and needed one, and while searching in the school library someone nearby recommended it to me because I was near its section. If I had heard about this book beforehand I would have probably chosen it because it is a good well-written story.
Synopsis:
Will is a fifteen year old boy who was raised as a ward in the Baron's castle because both of his parents were deceased by the time he was born. His father died, a great hero, and Will's one dream was to grow up becoming a knight for the kingdom. Once his choosing day comes, however, he is denied his position as a knight. Mysteriously enough Halt, a senior ranger, chooses Will as his Apprentice. Will's attributes are good, he is cunning and stealthy, which makes him perfect for being the essential “Spies” for the Kingdom. Once Will starts, he doesn't seem too interested in being a ranger, in fact he is crushed because of his want to become a knight. He quickly realizes though that rangers are not what they appear to be and he soon loves his new position as a ranger.
Morgarath is a Baron for another one of the kingdom's fiefs, Gorlan. Or he used to be. He tried to take over the kingdom but failed to do so, and he became banished to the Mountains of Rain and Night. After years of searching Morgarath found evil creatures called Kalkara, which are giant creatures similar to a big-foot. The Kalkara's eyes paralyze anyone within close range, and they are eventually deployed by Morgarath to go and seek revenge upon the kingdom which banished him. The rangers hear word that the Kalkara were coming from their tight network of spies, and Halt, Will and Halt's former apprentice Gilan are all going to attempt to kill them. After many suspenseful pages of tracking the Kalkara, Will is the one who end's up saving everyone's lives because of his quick thinking in a way to kill the Kalkara. In the end he is given the chance to become a knight again, and he denies it because of his newfound passion, being a ranger. Fortunately enough, the past of Will's parents were also revealed to him.
