Wolf of the Northern Star. The Wolfkin Saga, #2

Ghost is finally home. Back among his kind and learning what it means to be both a man and a shaman, Ghost battles the expectations of his people, his family, and the pressures of a society that is both foreign and familiar. His power is greater than any seen before, dwarfing that of even the legendary Shaman Gray Shadow-and his union with Kane places him in the center of a controversy that rattles wolfkin society around the world.
Ghost loves his mate and refuses to bow to mounting pressure to have them separated, and then Kane is falsely accused of forcing a mate bond. Kane, the alpha heir of his clan and Ghost's new mate, has finally defeated the traitor and murderer that destroyed the heart of Black Pine years before. Yet Kane has a new enemy to face: his own people. Placed on trial for violation of Law and blasphemy, Kane will have to fight to the death to preserve his bond with Ghost and keep his mate and people safe.
Alphas from far and wide come to the trial, some with the intent to take everything from Kane--including his beloved mate. A soulbound pair is traditionally seen as a blessing upon the wolfkin and their clans, yet their bond flies in the face of tradition. Ghost and Kane refuse to be parted, and even with the support of their friends and family, it may not be enough to preserve their mating when ancient laws and hatred threaten to destroy their love.
