Do the lesbians make it out alive?:

Yes, good ending, none of them die

So this book is a lot of fun. Has actual tension and gives enough of a background so you can piece together what caused this dystopian world. The character dynamics between the Homesteaders and Lynn are interesting, and I wish we saw more of it. 
The book is written well, but what kept it from the 5/5 for me was that the smut is written really awkwardly, and the last third isn't as captivating as the rest of the book.
