A Valkyrie's Vow

Sigrid, one of the illustrious Valkyries, has spent eons in Valhalla. When Odin sends her on a task, she can't get there fast enough. Until she lands on a horse ranch in Texas... Where's the battlefield? Who's the warrior she's to take back to Valhalla?
When Slade Larsen started taking in runaway boys, he honestly thought he was doing a good thing-giving them a place to stay and teaching them responsibility and a trade. But a couple of them came with more baggage than most, and it's bringing a new kind of danger he isn't prepared to deal with.
How is Sigi supposed to prepare Slade for his death when her feelings want him to live? Together, they battle dark forces that threaten to take over the boy's lives and Sigi fights to keep Slade from crossing a line that will damn him for eternity.
