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 Horace travels to the exotic land of Nihon-Ja, it isn't long before he finds himself pulled into a battle that is not his - but one he knows in his heart he must wage. A kingdom teeters on the edge of chaos when the Nihon-Ja emperor, a defender of the common man, is forcibly overthrown, and only Horace, Will, and his Araluen companions can restore the emperor to the throne. Victory lies in the hands of an inexperienced group of fighters, and it's anybody's guess who will make the journey home to Araluen.

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. 

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.

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.

John Flanagan returns to the world of Ranger’s Apprentice to find out what happens when Will’s apprentice, Maddie - the Royal Ranger - returns home to Castle Araluen. The Kingdom may have been at peace for a number of years, but there are always those who would commit treason to take power for themselves. When Maddie learns of a plot against the crown, she must go undercover to find out more - and hopefully stop it. But going undercover isn’t easy when you’re the princess - even if you’re trained as a Ranger. 

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.

What really happened at Hackham Heath that made Halt a hero to the entire Kingdom? This is the prequel Ranger's Apprentice fans have been waiting for. When the former Baron Morgarath escaped to avoid punishment for treason, an uneasy peace fell on Araluen. But the Rangers know Morgarath will be planning his next move, and there are rumours he has recruited an army of savage, inhuman creatures. Newly crowned King Duncan must prepare for war.

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.

Hal and the Herons have done the impossible. This group of outsiders has beaten out the strongest, most skilled young warriors in all of Skandia to win the Brotherband competition. But their celebration comes to an abrupt end when the Skandians' most sacred artifact, the Andomal, is stolen--and the Herons are to blame. To find redemption they must track down the thief Zavac and recover the Andomal. But that means traversing stormy seas, surviving a bitter winter, and battling a group of deadly pirates.
