Octopuppy, by Martin McKenna, Scholastic, 2015.
If this book hadn't have been on my son's teacher's wish list, I would not have picked it up. I was afraid it would be too gimicky. But it was on my son's teacher's wish list, and I did pick it up. And read it. And fell in love with story. And fell even more in love with the illustrations. So I bought it.
