I would just let her read through the book but have her narrate every few pages or so. My kids balk at having to do “enrichment” exercises when they really like the book. It sometimes sucks the fun out of it. If she is narrating very well every few pages then I would let well enough alone. I say a few pages only because that does force my kids to slow down and really pay attention and yet doesn’t stifle their interest.
IMHO there are days enough when the books to be read will not be all that interesting to the child and then, I guess, it is a good time to “buckle down”. If she enjoys horses I wouldn’t push her to make it “work”.
