I've read most of Grisham's books and enjoyed each one including The Exchange. It moved quickly, created plenty of suspense and developed characters enough for me to feel compassion (or otherwise) for them. It was odd to never find out what group held Giovanna for ransom and equally odd that Mitch fairly easily "allowed" his wife to set off for Marrakech. But still, due to Grisham's great writing, I couldn't put it down. Finished it in a few days. Good read!
