This book had me at post-apocalyptic. I admit, I’m a sucker for post-apocalyptic stories whether they’re books, movies, or just a good yarn. Now, Human Nature didn’t have Kevin Costner, but it was still a really good story. The real theme in this book is growth. The human race is growing stronger against the aliens. As she works on patching people up, Dawn grows more confident in herself and her skills – both as a doctor and as a leader. And, an unexpected love grows between Dawn and ________. Well, I can’t give it away, can I? I'll keep it on my reader because I may go back to it later when I need a post-apocalypse fix and don’t feel like watching The Postman or Legend. I’d definitely recommend it to a friend – they just may need to get their own copy!
