Time travel can be done poorly, as we all know. Thankfully, this one's a read-only copy, and I really enjoyed seeing good-ol' dad tinkering with the universe in ways much worse than his hapless kids. The backstory wraps the rest of the volumes into such a fantastically tight cocoon that I'm thrilled I stuck through the first volume. I suppose I ought to really thank the other peeps who turned me on to this whole tale. I might not have gotten as far without so many raving reviews. 
 I can't wait for the next volume, now.
