Gwen McMillan enjoys being a cop, has a partner she trusts with her life, and gets to enjoy her downtime at the end of each shift in her cozy farmhouse. The best part is, she’s far from her parents’ control and the life of privilege they lead. Despite the distance between her and her family, she’s honor-bound to keep their centuries-old secret hidden–protecting the fabled sword Excalibur until, as the legends foretold, King Arthur returns. Since becoming the blade’s guardian, Gwen’s had dreams about monsters, ancient kings, and mist-filled forests. And lately, these dreams center around an enigmatic, charming man she inexplicably feels drawn to. But when Gwen and Excalibur are magically swept away to Avalon, she lands in the middle of a war between humans and monsters. Mordred, the tyrannical ruler of the fae, is determined to conquer Avalon and rule over Arthur’s castle where a gateway to the human realm is hidden. Gwen joins the battle to save Camelot and protect the secret portal while trying to discover why she feels such a strong connection to Avalon’s magic.

That is, until Orin, one of Arthur’s knights, begins to pull at her heartstrings and her desire for a storybook kind of love. Their magnetic attraction to one another is undeniable.

Despite the ongoing war and Orin’s deep-seated fear of losing anyone else he loves, their romance blossoms. All hope for Camelot seems lost when the dark tyrant’s army draws closer to the castle gates. Gwen knows she holds the key to their salvation, but convincing Arthur to hand over Excalibur so she can use the blade to connect with Avalon’s magic proves difficult.

If Gwen can’t convince Arthur to hand over his fabled sword, she won’t be able to fulfill her destiny to protect Avalon . And if she can’t, Mordred will storm Camelot then conquer the entire mortal realm.

Every human in Avalon will be slaughtered, and not only will Gwen and Orin’s love be lost to time and history, so will the legacy of King Arthur.
