1. The A- Z Mysteries by Ron Roy.
They are straightforward and simple mysteries. Each book has an alliterative title. The Absent Author, the Talking T-Rex. The titles were enough to draw him in.
I think he liked it because it followed a particular formula and the chapters were short and easy enough for him to get through. The characters in the book carried through into the next book so he felt he knew the characters quite well by the end of the 3 week library loan period. And the sense of achievement from being able to read 2 or 3 of these in a day was tremendous for him. There are Super Editions which he didn't enjoy as much even though he read them as well.
