I picked this up from NetGalley. I liked the book. I enjoyed the characters and presentation of the plot more than I did Harry Turtledove's novel about the super volcano in Yellowstone.
The ending was a bit sudden- you are right in the climax of the novel when BOOM... the story jumps a few months ahead.
I am, however, only giving two and a half stars. The book was horrendously formatted and the price on Amazon says it will be$9.99. No ebook is worth that price, but that is a topic for another post. With that price, at the very least, it is not acceptable to have the errors in the formatting (spaces within words, capital letters that should not be capitalized, the title showing up mid-paragraph, etc.).
I get that some of these copies are advance copies, but people/publishers need to be more careful with the quality. I get there will be some errors and some things might be changed, but the amount of errors in this was ridiculous.
I cannot recommend unless a person is able to return the book, so look carefully if you do decide to purchase.
