The New York Times best-selling series continues with another nail-biting mission for Will Treaty and his fearless young apprentice. King Philippe of Gallica appeals to King Duncan for help. His son is being held hostage by a power-hungry baron, and Philippe wants Duncan to send a Ranger to rescue the boy. Will and Maddie are perfect for the task. Travelling as father and daughter to allay suspicion, they will pose as entertainers to infiltrate the Chateau des Falaises, where the prince is being held. 

The Ranger's Apprentice origin story fans have been waiting for. Before they became the most famous Ranger in the land and the hard-working Ranger Commandant, Halt and Crowley were young friends determined to change the world. The scheming Baron Morgarath is drawing other power-hungry knights and barons to his banner. King Oswald is wasting away, and, if gossip can be believed, Prince Duncan is causing havoc in the north.

Unconfirmed accounts of a group of Araluen warriors - tales of adventure, battle, and triumph over evil - have spread for centuries throughout the known world. Most notable is a clan shrouded in mystery, phantom warriors known as the Rangers. Two names pass the lips of every storyteller: Halt, and his apprentice, Will. They and their comrades in arms are said to have traveled throughout the kingdom and beyond its borders, protecting those who needed it most.

What does it mean to earn the silver oakleaf? So few men have done so. For Will, a mere boy, that symbol of honor has long felt out of reach. Now, in the wake of Araluen's uneasy truce with the raiding Skandians comes word that the Skandian leader has been captured by a dangerous desert tribe. The Rangers are sent to free him. But the desert is like nothing these warriors have seen before. Strangers in a strange land, they are brutalized by sandstorms, beaten by the unrelenting heat, tricked by one tribe that plays by its own rules, and surprisingly befriended by another. 

In Skandia, there is only one way to become a warrior. Boys are chosen for teams called brotherbands and must endure three months of gruelling training in seamanship, weapons and battle tactics. It's brotherband against brotherband, fighting it out in a series of challenges. There can be only one winner. When Hal Mikkelson finds himself the unwilling leader of a brotherband made up of outcasts, he must step up to the challenge.

Mankind puts its faith in many things - gods, kings, money - anything for protection from the worlds many dangers. When a cult springs up in neighboring Clonmel, promising to quell the recent attacks by lawless marauders, people flock to offer gold in exchange for protection. But this particular group, with which Halt is all too familiar, has a less than charitable agenda. Secrets will be unveiled and battles fought to the death as Will and Horace help Halt in ridding the land of a dangerous enemy.

The renegade outlaw group known as the Outsiders may have been chased from Clonmel, but not before killing Halt's only brother. Now Rangers Halt and Will, along with the young warrior Horace, are in pursuit. The Outsiders have done an effective job of dividing the kingdom into factions and are looking to overtake Araluen. It will take every bit of skill and cunning for the Rangers to survive. Some may not be so lucky.

When the worlds of Ranger's Apprentice and Brotherband cross over, action and adventure are guaranteed!King Duncan of Araluen has an urgent mission for Hal and the Heron brotherband. One assassination attempt on his daughter Cassandra was foiled – but the would-be killers are from the deadly Scorpion cult, and they won't be satisfied until they have completed their task. The Herons team up with Ranger Gilan to track the killers across the deserts of Arrida and infiltrate their mountain lair.

After years as a Ranger's apprentice, Will is now the protector of his first fief. Not long into his service, everything that can go wrong does: Keren, a renegade knight, has taken over Castle Macindaw, a strategic gateway to the North - poisoning the royal family in the process - and is holding Will's friend Alyss captive. The situation grows direr when Will uncovers Keren's secret alliance with the Scotti, who have plans to plunder Araluen. Time is of the essence; Will must recruit a motley crew to rescue Alyss and reclaim Castle Macindaw - before the Scotti can make it their own.

Several years have passed since the apprentice and his master, Will and Halt, first met, and Will is finally a full-fledged Ranger with his own fief to look after. The fief seems sleepy - boring, even - until Lord Syron, master of a castle far in the north, is struck down by a mysterious illness. Joined by his friend Alyss, Will is suddenly thrown headfirst into an extraordinary adventure, investigating fears of sorcery and trying to determine who is loyal to Lord Syron.
