Publisher's Summary
Fourteen-year old Anakin has proven his affinity for the Force, and his amazing reflexes and physical skills, but he still has much to learn. It is up to Obi-Wan Kenobi to mold the possible Chosen One into a great Jedi Knight. On a mission to a world poisoned by a toxic disaster, Master and Padawan are separated. Anakin and three other young apprentices -- including Anakin's rival -- must work together to survive. Anakin's competitive instincts may be his undoing.
