Death in the Night by Allyson Lindt

Every lover. Every betrayal. Every death.
Kirby remembers it all. The gods will pay for the suffering they’ve caused in this life and those she’s lived before. The only questions are where and how?
She has new allies and lovers, but with a lifetime of betrayal guiding her, she doesn’t know who to turn to. The trickster god who makes it easy to throw caution to the wind? The god of passion who sparks delight, terror, and desire with a single look?
Kirby desperately wants one of those people she trusts to be the berserker who set her on this path both then and now, but lifetimes of playing both sides changes a person.
Time is running out for her to find answers. Both about her lovers, and the gods she seeks to destroy before they can act on the prophecies that will allow them to topple modern empires.
Failure means not just her destruction, but the death of thousands.
