Erak's Ransom (The Ranger's Apprentice, Book 7)

When Erak, the Skandian Oberjarl, is taken hostage during a raid on the desert lands to the south of the Constant Sea, his second-in-command, Svengal, is sent to bring back a ransom for Erak's release. Halt and Will must go with Svengal to deliver the ransom and secure Erak's freedom, but a royal presence is needed too. The Princess Cassandra - or Evanlyn, as Will knows her - persuades her father to let her go with them. Horace and the Ranger Gilan round out the group to make sure that Evanlyn is well protected.

The Icebound Land (The Ranger's Apprentice, Book 3)

Kidnapped after the fierce battle with Lord Morgarath, Will and Evanlyn are bound for Skandia as captives aboard a fearsome wolfship. Halt has sworn to rescue Will, and he will do anything to keep his promise--even defy his King.

Expelled from the Rangers he has served so loyally, Halt is joined by Will's friend Horace as he travels toward Skandia. On their way, they are challenged constantly by freelance knights--but Horace knows a thing or two about combat. Soon he begins to attract the attention of knights and warlords for miles around with his uncanny skill. Even so, will they be in time to rescue Will from a horrific life of slavery?

The Burning Bridge (The Ranger's Apprentice, Book 2)

Bracing for a final clash with the evil warlord Morgarath, the Rangers rally the kingdom's allies, and Will is chosen, along with his friend Horace, as special envoys to nearby Celtica. But the simple mission soon takes an unsettling turn - the Celticans have disappeared, their town abandoned. The scheming hand of Morgarath, it seems, has been far from idle. He has found a way to bring his legions over the once impassible eastern mountains and is planning to ambush the king's army in a rout. 

The Sorcerer of the North (The Ranger's Apprentice, Book 5)

Will is just settling into his first post as a brand-new, just-commissioned Ranger when he is dispatched to deal with problems on the kingdom’s northern border. Though his keen senses and uncanny expertise with his knives and his bow are vital, Will’s success often hinges on his ability to assess the skills and intentions of those around him. The scenes involving Will, his mentor, Halt, and Halt’s mentor, Crowley, work beautifully to fill in background information, dramatize Will’s growing maturity, and entertain readers with clever dialogue. The Sorcerer of the North is a must-have volume for fans of the popular Ranger’s Apprentice series

When a cult springs up in neighboring Clonmel, promising to quell the recent attacks by lawless marauders, people flock from all over 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 worldwide phenomenon is back with a gripping new adventure.

Yet for these Rangers, the peril is only beginning...
