"The Exchange: After The Firm" by John Grisham. I generally like Grisham's books but was really let down by this one. Book claims to be a sequel to The Firm. Technically it features two of the characters from The Firm, Mitch and Abby McDeere, and it takes place after the events of The Firm, in fact, fifteen years after. (Is it really a sequel if it's 15 years later and there is nothing remotely resembling the original story?)
The plot is ridiculous. The events from about mid-way through the book to the end resolution would never happen in a million years. There is no action, just descriptions of things that happened on videotape. Pages and pages and pages describe Mitch on an airplane, Mitch on the phone, Mitch in hotels in foreign countries, Mitch in meetings, Mitch eating breakfast, lunch, dinner, etc. etc. On and on and on with this stuff.
I started skimming pages. Then I started skipping pages. I didn't miss anything. If this wasn't sold as being a sequel to The Firm I would have quit reading, probably about half way through.
In short, it was a gigantic waste of my time that I could have better spent reading something good.
