The story line in this book is a good one, it’s fast paced and the science is interesting ….it’s too bad that the main characters turn out to be no better than the muggers and thieves. This could have been a much better book without so much physical violence and bias and negativity. Yes, that would be part of what would go on in this scenario but the mother admits she’s racist, the daughter beats up a mugger so badly she broke his bones and kept at it. They say they are Christian but you could have fooled me. Enjoyed the story line but that’s it!
