Thank you, Val, what a wonderful idea!

I thought I'd start by mentioning one of my all-time favourites: "Wolf Story" by William McCleery (illustrations by Warren Chappell) c. 1947. It's a great read-aloud for ages probably 2 to 7 or 8 or so, and Harpo enjoyed reading it on his own when he was about 4 and 5.

It's funny and sweet. In a series of installments that starts one night at bedtime, a father tells his smart and rather crafty five-year-old son Michael a story about a hen named Rainbow, Waldo the wolf, and a bright and brave young farm lad named Jimmy Tractorwheel. Michael and his six-year-old best friend Stefan suggest various plot twists as the story unfolds; each installment is accompanied by a certain amount of negotiation with Michael's inventive father.

It's 82 pages, with charming black and white drawings; it has a nice amount of white space on the page, and a generous size of type and amount of leading for a young reader. I'd say it's a good early venture into chapter books.
