I'm attaching the epub in question.
As an example, the first unwanted break occurs at the end of the split_003.html:
<p class="MsoNormal8">There came a day – not long before Halloween, because Little Pete'd put up a paper witch in the entry window, I remember – when I was supposed to go down to the Strayhorn place after lunch. Me and Lisa McCandless were going to turn those fancy Persian rugs downstairs – you're supposed to do that every six months so they won't fade, or so they'll fade even, or some damned thing. I put my coat on and got it buttoned and was halfway to the door when I thought, What are you doin with this heavy fall coat on, you foolish thing? It's sixty-five degrees out there, at least, real Indian Summer weather. And this other voice come back and said, It won't be sixty-five out on the reach; it'll be more like fifty out there. Damp, too. And that's how I come to know I wasn't goin anywhere near the Strayhorn place that afternoon. I was gonna take the ferry across to Jonesport instead, and have it out with my daughter. I called Lisa, told her we'd have to do the rugs another day, and left for the ferry landin. I was just in time to catch the two-fifteen. If I'd missed it, I might've missed <i class="calibre2">her,</i> and who knows how different things might have turned out then?</p>
