I actually really enjoyed this book. After reading other reviews I was skeptical, but ended up being pleasantly surprised by this book. It's fairly short, I was able to read it in a couple of hours, but I felt like I did get a good grasp of the story. The story line moves along quickly. I thought this was an interesting take on the end-of-days. I also felt like the author stayed true to the mentality of the heroine. I read some reviews that complained of her happy disposition after all she's been through... I felt it was a genuine reaction. After being alone for so long, wouldn't we all crave camaraderie?
This could have been dragged out into a "The Stand"-ish book, but I feel like the length of the book was perfect for this story.
I almost lean towards 5 stars here.
Oh, and I rarely write more than one sentence per review - this book definitely got me thinking.
An enjoyable evening read.
