Childish from start to finish.
Right off the bat I was annoyed by the story. The introduction plays up the whole Global Warming theory and how it amplifies magic. Then in the first chapter the weather hasn't changed at all. Which is it? Either you have global warming or you don't! If it's warm enough to melt glaciers, then there wouldn't be frozen lakes and snow in Minnesota.
Which leads to the next annoyance. The author refuses to take displacement into account when they tote the whole crust of the Earth shifting. It doesn't make any sense. And the Earth's crust shifts constantly so these so-called ley lines wouldn't just "suddenly" appear.
Then there is the magic. It's supposed to be rampant, yet it's secretive throughout the book. They're so concerned about keeping it quiet, its absurd! And if Sig can detect black magic, why didn't he detect it with the girl/witch? Seems like she would emanate the smell of it as well.
I had a hard time trying to figure out how old Sig is. At times he acts like he is 12, but then his mom lets him have a beer. They talk about college, but treat him like he's 14. It doesn't seem to follow a proper age designation.
I also hated Sig. Right from the beginning he makes himself out to be a chauvinistic pig. "Women warriors. Isn't that an oxymoron?" Really makes you hate him, especially since Norse mythology(which the story is based upon) has women warriors.
And the tractor! The mother can operate it, in a life or death situation, just by her past observation? No way! Not believable at all! I know from experience it isn't that simple, and that leads to my next question: who takes care of the farm? Who does all the work? The mother doesn't. The Dad is gone. And Sig certainly doesn't. So who does it all? Obviously they would have to employ several people for the large farm they have, but there is never any mention of anyone.
The lack if concern for shifting boulders was childish. Whenever you have a cave in, you have to consider possible shifts very carefully, and they didn't. Plus, the boulders described are too large for the truck to pull, unless they are already tipping over, but it sounds like they were pretty stuck, so it doesn't quite work. Too many assumptions behind this work.
The whole story feel likes a first draft. And there were words thrown in that just didn't fit. Congratulations! You know a big word and how to use it, but that doesn't mean it fits in this particular sentence.
Another annoyance was the information thrown in that was completely irrelevant to the story. The Jaguar is special, but it isn't relevant! It doesn't give us anything pertinent to the plot, or character, so why go on about it?
Definitely would not recommend this to anyone, not unless it gets a major overhaul. If I could give it 0 stars I would.
The grammar:
Awful. Just awful. Wrong tense, missing words, strange phrasing, words used in the wrong places, and added words. Phrases are repeated over and over again. I got so tired of "I've got your back" I never want to hear or read the phrase again! Reads like a first draft and needs major editing.
For my clean readers:
Language, violence, discussion of cleavage(teenage boy hormones), underage drinking, and discussion of teenage cigarette use.
