"Will Treaty has come a long way from the small boy with dreams of knighthood. Life had other plans for him, and as an apprentice Ranger under Halt, he grew into a legend--the finest Ranger the kingdom had ever known. But now it's time to take on an apprentice of his own, and it's the last person he ever would have expected: his niece and goddaughter Maddie. But Maddie is more than Will bargained for, and with time, he must win the trust and respect...

Maddie, Will Treaty's fearless young apprentice, aided by Hal, Thorn, and the rest of the Heron Brotherband, tries to rescue her mother, Princess Cassandra, who is trapped in Castle Araluen.

Held captive by the dangerous baron Lassigny, Will Treaty and his fearless young apprentice, Maddie, must outwit the baron with the help of their friends from home to escape.
