Nixing the End of the World by Alice Winters

Nix:
“You are the savior of mankind” are the last words I ever expected to hear while nibbling on fries. The thing is, I’m not mankind saving material. I don’t even have magic (and just found out it exists). I’m the most boring, normal(ish) human ever.
Suddenly, I’m being tossed right into the middle of a fight that started years before I was even born, and then I get partnered up with Alastair, a quirky magical Guardian. He is rather attractive and sweet when he’s not into the whole “woe is me, I can’t let myself fall in love with you” nonsense. I mean, the moment he took my annoyingly judgmental grandma hostage, it was all over for me. I was hooked.
Now the only problem is… what exactly are we saving the world from?

Alastair:
The moment I laid eyes on Nix, the naive yet easygoing human captivated my attention, and now I’m determined to protect him. But despite my amazing and majestic abilities, we might not make it out of this mess. Still, there must be a reason Nix was chosen. No, he doesn’t have pizazz and maybe he really doesn’t have magic, but he’s also one of the strongest and kindest men I’ve ever met.
Now if I can just get him to stop throwing blankets at enemies, we might have a shot at this.
