After a year of adjusting to having shamanic powers, Joanne Walker has leveled up-and now she's got to start all over again. She's more open to the idea now, but it means throwing caution to the wind.

Caution, and her job, and her potential relationship with her former boss...and possibly any hope for a future tied to a timeline she recognizes at all. Determined to heal herself of a magically-inflicted injury, Joanne returns to her ancestral homeland-and when she activates her newly-increased powers, Ireland's ancient, deep magic rips her out of time and into a history of regrets and unfinished business.

The aos sí of Irish legend-the fair folk, gods, and heroes of old-have paid the price of tangling with a dark power who stands against everything Joanne has ever believed in...and her ability to protect them is stymied by what she's already done to save others. As the consequences of her actions begin to build up,

Joanne is faced with two impossible choices-and loses her beloved best friend Gary to one, leaving her to face the other alone.

And as dark magic devours her from within, Joanne must risk everything to destroy the monster her mother has become-or fight the gods themselves to save her.
