The Last Valkyrie by KC Kingmaker

I have been revealed as something not seen since the Dark Ages. Yet even my newfound powers might not be enough to save our world.

War is coming to Vikingrune Academy. For the first time in centuries, malevolent races from other worlds have landed in Midgard—dark elves, giants, and even something more diabolical beneath the earth.
It’s all hands on deck as we race toward the inevitable. The academy is sorely unprepared after spending months underground during the frosty winter. My mates and I find warmth with each other, but we need allies, which means begging for help from anyone who will listen.
Of course, nothing comes without a price. The cost of an alliance will be steep. Even then we may only have our fellow Vikingruners to rely on. It means putting aside petty squabbles, which is much easier said than done when family is involved. Case in point: I received a cryptic letter from my mother, far away from the Isle. My meeting with her will change everything.
We need a leader, because the Gothi can’t be trusted. After discovering what I am, I feel I finally have the tools to unify the many races of the realms. But with danger and betrayal at every turn, will I even get the chance before it’s too late and Midgard falls?

(The Last Valkyrie is the final book in “Vikingrune Academy.” The action is more intense, the stakes higher, and the betrayals deeper than ever before. In this why choose paranormal romance series, no one is safe. Please read the trigger warnings before embarking on this wild, violent, steamy journey!)
