Eager to return to his native Norway, Thorgrim agrees to participate in one last raid under the command of a man he does not trust. But the Northmen, he finds, are no longer simply invaders on foreign soil. They have become a part of the Irish kings' ongoing struggle for power, and, far from securing a means to return home, Thorgrim and his men are plunged into a battle for the throne of Tara - a battle that will test their strength and loyalty as none has before.

Having recovered from the wounds of battle and having won for himself a fortune, a crew, and a longship, Thorgrim Night Wolf makes ready to leave the Viking town of Dubh-linn for the long journey back to his home in Norway. But the gods have other plans, and Thorgrim and his men wash up in the small Viking longphort of Vík-ló. Thinking themselves among friends, they soon learn that the opposite is true - that Grimarr Giant, the Lord of Vík-ló, has reason to want Thorgrim and his son, Harald, dead.

Spring has come to Ireland, where Thorgrim Night Wolf, new-made Lord of Vík-ló, and the 300 Viking warriors under his command have suffered through a brutal winter. Despite having accomplished much during the months of cold and rain, the patience of the men has worn thin, and anger and frustration threaten to tear the ships' crews apart. But just as the men are turning on one another, a local Irish lord arrives with a proposal, a plan for Irish and Norse to join together in a raid.

Summer comes to Ireland, and an uneasy peace holds at Loch Garman. The Northmen, eager to get to sea, work relentlessly on their ships, with the aid of their unlikely allies, the Irish, who are just as eager to see them go. But not everyone is willing to just let them sail away. Certain that God demands the heathens be punished, the one-eyed warrior turned monk Brother Becc is determined that Thorgrim and his men will not simply go free. And when another band of raiders arrives, Becc finds the excuse he needs to take action.  

With their ill-fated raid on the monastary at Glendalough torn apart by betrayal and defeat, Thorgrim Night Wolf and his handful of survivors from the crew of Sea Hammer find themselves in desperate and tenuous straits. Stranded far from the safety of Vik-lo, surrounded by enemies, and with barely enough men to work the longship's oars, the Norsemen must make their way back through a dangerous and uncertain country. Thorgrim, however, is not interested in mere survival. His one thought, his one desire, is to take revenge.

After the treachery and slaughter they met during the raid on Glendalough, Thorgrim Night Wolf and his small band of surviving Northmen have returned to Vik-lo, where Thorgrim again sits as lord of the Viking longphort. But the Northmen are a restless lot, and soon they find themselves eager to put to sea. Loading weapons and supplies aboard the four longships under Thorgrim's command, they set out in search of the rich merchant ships that now ply Irish waters. But not all cargoes are the same, nor all merchant captains easy targets for the Norse raiders.

Thorgrim Night Wolf, now somewhere on the south coast of Engla-land, may be closer to his goal of returning home than he has been since reaching Ireland years before, but he is still very, very far away. His son Harald, however, has ambitions beyond just getting home. Given command of one of the ships in the fleet, Harald sees a chance to put his courage on display, unleashing consequences that will lead Thorgrim into a fight against the powerful armies of Wessex, a fight he does not want.

Driven ashore on the coast of Ireland, their longships nearly wrecked by the gods who seem unwilling to let them leave, Thorgrim Night Wolf and his band of Northmen once again face a fight for their survival. Helpless without their ships, they must find some refuge in that hostile country and begin the laborious work of making the vessels seaworthy again. But for all the shipbuilding skills that Thorgrim and the others possess, there is one thing they cannot do - weave cloth to replace the sails shredded in the gale that drove them ashore.  

1179. Henry II's Norman conquerors have swept through England, Wales - and now Ireland. Irish nobleman Ferdia has been imprisoned in Wales to ensure the good behaviour of his rebellious father. But during a skirmish on a neighbouring castle, Ferdia saves the life of the man who would become one of the most legendary warriors to have ever lived: Richard Plantagenet. The Lionheart. 

Beobrand is besieged in the action-packed instalment in the Bernicia Chronicles set in AD 647 Anglo-Saxon Britain. War hangs heavy in the hot summer air as Penda of Mercia and his allies march into the north. Caught unawares, the Bernician forces are besieged within the great fortress of Bebbanburg. It falls to Beobrand to mount the defence of the stronghold, but even while the battle rages, old and powerful enemies have mobilised against him, seeking vengeance for past events.

In the Orkney Isles, a young woman flees her home to save the life of her unborn child. Eighteen years later, a witch foretells that evil from her past is reaching out again to threaten her son. Outlawed from his home in Iceland, Einar Unnsson is thrown on the mercy of his uncle, the infamous Jarl Thorfinn ‘Skull Cleaver’ of Orkney.

King Horic is dead. The oaths that once bonded the Danes and Northmen in the islands of Aquitaine have broken. Hasting's new land is imperiled by fearsome challengers and old foes alike. A rumor from the continent will shatter the brittle veneer of his strength and expose his deepest wound from the past. His greatest trial will not be fought with a sword, ax, or shield, but with his heart.

England, 1346. For Thomas Blackstone the choice is easy - dance on the end of a rope for a murder he did not commit, or join the king's invasion. As he fights his way across northern France, Blackstone learns the brutal lessons of war. Vastly outnumbered, Edward III's army will finally confront the armoured might of the French nobility on the field of Crécy. It is a battle that will change the history of warfare.

Beobrand is compelled by his brother's almost-certain murder to embark on a quest for revenge in the war-ravaged kingdoms of Northumbria. The land is rife with danger, as warlords vie for supremacy and dominion. In the battles for control of the region, new oaths are made and broken, and loyalties are tested to the limits. With no patronage and no experience, Beobrand must form his own allegiances and learn to fight with sword and shield. Relentless in pursuit of his enemies, he faces challenges which transform him from a boy to a man.

Winter, 1364. Sir Thomas Blackstone, Edward III's Master of War, has travelled to France to secure Brittany for England. In the throes of battle, he rescues a Castilian boy, Lazaro, who just witnessed the murder of the young queen. It is suspected that the king - along with Velasquita Alcon de Lugo, the beautiful witch who serves him - assassinated his queen. But Lazaro knows that is not the case. With the king in hiding and the French army advancing Castile is on its knees. So Blackstone is ordered to Castile, to defend England's ally from the French.
