The last Connie Willis book I read (Passage) was all about missed, vague, or unreliable communication. This one is all about having too much communication, per the title, and had a hectic feel to parts of it which really got the point across but also sometimes made it a bit tough to read. For those who fund the introductory chapter a little difficult (detailing a woman trying to deal with too many text messages, phone calls, and other interruptions) know that it smooths out at least somewhat and turns into a really fascinating story about how we talk to one another and know about each other.
