On a Beam of Light, Jennifer Berne
This is a stellar book. Albert Einstein stars as an unusual character who thought great thoughts, and it reads so well as a children's tale! I think it is an utterly wonderful idea for a book and I cannot applaud it enough! Berne, you are brilliant!
Mister Seahorse, Eric Carle
I hadn't seen this! I think most of Carle's books have something appealing. This one has interesting facts woven into the story, and it is such a sweet delivery of those facts via parallel construction, garnished with good manners. It also features transparent pages, like Dream Snow.
A Mummy for Owen, Marion Dane Bauer
Based on a true story of wildlife adoption, I was charmed by this tale (although there's some sadness in it, too). It is a great discussion-starter for this age.
