A first adventure novel needs a goal you can say in one sentence. Find the dragon. Get the motorcycle back. See what is in the boxcar. If the child can tell you the goal, they can pick the book up again tomorrow.
My Father\'s Dragon and Flat Stanley are the short ones. The Mouse and the Motorcycle and The Boxcar Children take a few nights. James and the Giant Peach and The BFG are the read-alouds for when you want a bigger story and you are willing to do the voices.
Stop at the end of a chapter even if they beg. The begging means the book is working. Mark the page. A child who knows you will come back is more willing to wait.
If the book stalls for three nights, switch. An adventure they do not care about will not become interesting because you push through chapter six.
Keep a bookmark in it, even if they say they will remember the page. Tomorrow the goal should still be obvious, and the bookmark is what makes that true.
