A secret brotherhood of treasure hunters. An invading army coming ever closer. Five young apprentices. The race is on. Life as a thief is cold, miserable and hungry. Caspan leaps at the opportunity to compete to join the Brotherhood of Thieves – a secret order sanctioned by the king. What the Brotherhood seeks are the lost magical weapons of an ancient race that will help them defeat the Roon, the invading army who creep ever closer. Defeat seems inevitable. Unless Caspan and his fellow recruits – Roland, Lachlan, Sara and Kilt – can set aside their differences and use their new skills to help turn the tide. With swords strapped to their belts, riding magical beasts called Wardens that come only to their call, they leave the sanctuary of their training ground for their first mission. Will it be their last?
