Peace between the Nine Realms comes at a price. Princess Lyra Eirsdóttir of Vanaheim is sent to Asgard to fulfil an ancient treaty, binding her future to Prince Loki in a marriage neither of them chose. To the realms, their union is a symbol of hope. To them, it is another chain forged by duty. But as political tensions rise, forgotten enemies emerge from the shadows, and the fragile peace begins to crack, Lyra and Loki discover that trust is far more dangerous than war. Sometimes the strongest alliances aren't written in treaties... They're written in the hearts of those brave enough to choose each other.
Kaia Vale never wanted to be an Alpha—especially not the Alpha. Chosen by an ancient power she doesn't understand, Kaia suddenly finds herself at the centre of a supernatural hierarchy that believes she has no right to exist, while S.H.I.E.L.D. seems to know far more about her new abilities than they're willing to admit. Her solution? Handle it alone. Nick Fury's solution? Give her the Avengers. Now Kaia has a billionaire asking invasive questions, a super-soldier questioning her decisions, a witch who can see straight through her, a god who immediately declares himself part of her pack, a trickster who insists he absolutely isn't, and Bucky Barnes quietly becoming the one person she trusts to stand at her side. But when something begins hunting Alphas, Kaia's instincts make one thing dangerously clear: The Avengers aren't just her allies anymore. They're her pack. And you should never threaten an Alpha's pack.
