Norse Code by Greg van Eekhout is a weird little book. If you don't know anything about Norse mythology you might not understand some of what is going on. If Norse gods are part of your spiritual practise you might not be happy with how they are characterized.
NorseCODE is a DNA company run by Valkyrie. It's purpose is to find the human progenyof Odin and turn them into warriors for the final battle of Ragnarok. Anyone who does not agree to be a warrior is killed. No explanation as to why.
A Valkyrie, with the unbelievable name of Mist, wants to free her sister from Hel's realm. To do this she tracks down the only being ever to return alive: the god Hermod. For his part, Hermod is having a bad day. He may have just released the wolves that eat the sun and the moon which leads to the destruction of Earth (and everything else.)
This book is part urban fantasy, part science fiction and part mystery. I'm not sure the combination was entirely successful. It has got some very funny moments in it. While I liked the book I thought it tried a little too hard sometimes. Maybe it's just that I thought Ragnarok would have had a lot more going on.
