July in Houston, Texas, is far too hot for Frost Giants. But when a Valkyrie with an attitude shows up on Marti Keller's doorstep in the middle of summer, things take a turn for the polar. After Marti returned home from her ordeal at the hands of a notorious drug and human trafficker, she had expected her life to return to its normal placid state, maybe with the addition of a splash of romance. Instead, she finds she's hopped out of the frying pan and into the Arctic Circle, where she lands square in the middle of an ancient apocalyptic prophecy. Can a tiny tweak of the prophecy change the fate of the world? She'll find out, if she lives long enough to make it to Ragnoräk.
