I thought that this was an amazingly written, and truly unique book. It flowed together nicely, especially with the authors writing alternating chapters. This is the first book I've read by the two, so I think I may have to pick up their last two books written together, as well as their books written solo. The one thing that I had a problem with was their dissing of Nicholas Sparks. I mean, really! Ugh, I love him and this book, which is definitely worth the read!
