We're close to spring. I can feel it. This may very well be the most mild winter I've ever experienced. It's not even March and already I can see little bits of green poking up in my flower gardens as my daffodils and tulips emerge. This has put me in a mood for the color green! So, for this week's puzzler, I've collected ten green covers of popular picture books. Can you name each book from the small glimpse of its cover? Put your guesses in the comments below and I'll be back at the end of the week with the answers. Think spring!
