The Magic Thief by Sarah Prineas
Rating:I really liked this book. The story was simple but engaging, and the characters were interesting and unique. I was hooked from the very beginning.
Description:Conn has grown up in the slums of a magical city, picking pockets and locks for a living. He has always been able to escape the notice of the cities powerful rulers until he unknowingly stole a wizard's magical stone. The stone should have killed Conn on contact, but for some reason it did not hurt him. Nevery, the wizard whose stone Conn stole, took an interest in Conn, and decided to take Conn on as his apprentice. To continue his apprenticeship with the wizard Conn must find his own locus magicalicus.
