I blame the author, Karyn. I've been told that he's something of an Idjit. He's not going to be entrusted with such responsibilities in the future. When the next book is finished, he'll humbly ask for volunteers to proofread it before it is inflicted on an unsuspecting public. A few of my Coffeehouse friends have been very helpful in pointing out some brain glitches.
Also, I share your daughter's disappointment. My printed copy isn't signed either.
