The Good Ship Reverence

I was hooked from the first page! I received an arc copy, and added it to my kindle. I just opened up the book to make sure it loaded, not intending to start it yet, but I was sucked in and read the first couple chapters. Dismissing scientific inaccuracies, it was an intriguing story about a nearly destroyed Earth and two warring ark-style generational ships; both unwilling or unable to leave Earth because of the other one.
