I found Two Nights quite interesting. It did take a few chapters to become engaging but then it zoomed forward to "I can't put this book down".
As much I like and always look forward to the 'Tempe Brennan' novels I'm glad Kathy Reichs took a break from them. Tempe was getting a bit angry and jaded. She needed this vacation. That said I sincerely hope Two Nights is not a stand alone novel but the beginning of another direction and a new series from Kathy Reichs. That would be a wealth of riches from her.
