Title for Viking Novel?

I'm writing a novel and it kinda revolves around Viking mythology. So there's the good gods and the bad gods and they're in the modern times. They realize that their descendants (teens) are becoming friends and they're not supposed to. So the Viking gods are going to come to "the real world" and set things straight. But then there's a huge 3-sided war. The sides are good gods, bad gods, and humans. I think it'll be a really good novel, and I'd like for you guys to recommend a title for my novel that's both catchy and makes sense. I'm only 13, so no profanity. Thanks! I appreciate it!
