This is one of those books where you think it'll be a good idea to "read as a couple" but then, after a few pages, and some "oh, we do that"s becoming "Oh, we do do that" you won't be so sure.
Some couples wonder if they have the mettle for a committed relationship, or the momentum for long-distance love, or the reflexes for fighting crime. Unsure couples waste years looking for answers in each other's eyes, or in the offices of behavioral therapists. And yet each night their sleeping bodies reveal more than any doctor or private detective could ever discover.
