Choosing the Slain - Amy Cissell - Bog

Life sucks, and then you die. Usually.
Last week, Frankie had a great job and an amazing fiancée. Now she's sleeping in a storage closet and taking advice from a talking cat.
A timely warning sends her rushing into a burning building. Choosing to save the woman she loves and condemning an innocent to death wakes the Valkyrie power she never knew she had.
Frankie can choose who lives and who dies, and that draws the attention of exiled gods looking for a way back to Earth. If she doesn't learn the rules and choose sides fast, the world will burn, and Ragnarok will begin.
