Well, this was a very interesting premise for a book - sort of a darker version of Grimwood's _Into The Deep_. The dolphins were certainly not cute and cuddly. It was a rather grim, but fascinating story. As it moved through time, it was a bit... abrupt. The story didn't flow all that smoothly, but it certainly was interesting. Although, Jablokov's 2015 was not remotely similar to Back to the Future Part II's 2015 - not a hoverboard or flying car in sight!
