Avoiding Valhalla

Adam keeps seeing one particular soldier nearby. No one else seems to notice. Since Afghanistan is a hot zone, there's no avoiding a certain amount of death so Adam sees the mysterious unidentified soldier multiple times.

Then, while in the field, Adam's vehicle gets hit. Everyone but Adam dies. The unknown soldier rescues Adam from certain death. Sig isn't what he looks like, hot as that is,--or maybe it's that he's more than he seems. Can an immortal Valkyrie and an all too human military doctor find some way to overcome impossible obstacles to find happiness together? What price will Sig have to pay? It's not going to be that easy to walk away from being an angel of death.
