On the grim death world of Fenris, the Space Wolves Chapter selects its aspirants from the best and brightest of the young tribesmen. Ragnar of the Thunderfist tribe finds his life changed forever when he is chosen. After being revived from a savage death on the battlefield, Ragnar is recruited into the fearsome Space Wolves Chapter. He is then thrown into a galactic war against the dark forces of Chaos. However, the implanting of the Canis Helix unleashes his primal instincts and Ragnar must fight to control the beast within him.

A deadly plague is ravaging the planet of Aerius, and millions of Imperial citizens are dying. Inquisitor Sternberg turns to the fearsome Space Wolves for aid in recovering the ancient Talisman of Lykos, which he believes can cure the corruption ravaging the world. Ragnar Blackmane and his squad of Blood Claws embark on a near-suicidal mission to retrieve the talisman before it is too late. But this is no ordinary plague, and the servants of Nurgle await the Space Wolves. Will they be able to overcome the forces of Chaos, or is Aerius doomed?

Ragnar Blackmane is unique among the Space Wolves in ascending to the Wolf Guard without ever being a Grey Hunter. But how did he manage such a feat? The beginnings of that story are told here. When the Spear of Russ, an ancient relic of the Space Wolves once wielded by Leman Russ himself, is stolen, the Chapter seeks its return on the world of Garm. But when the forces of Chaos ambush them, the enraged Space Wolves learn that there is more to the attack than they could have guessed, for an ancient enemy of the Chapter is prophesied to be reborn.

Can these stubborn warriors put their differences aside and unite to face a common foe?

For ten thousand years, the Thousand Sons have sought revenge upon the Space Wolves for the destruction of their home world of Prospero. Now, the time may have come for their final victory.

With the aid of brothers long thought lost, Ragnar seeks to retrieve the Spear of Russ, and not only save the day, but regain his honour.
