I never really discovered children's books till I was in my 20's. I certainly had lots of favorites as a kid but never really got too interested in them until I went to college. I discovered this great series of books about two toad brothers called "Warton and Morton" by Russell E Erickson. If you know the series you probably know the first book titled "Toad for Tuesday" which is still in print.
The whole series was amazing and I loved reading about what trouble these two got into. I think there were 6 or 7 published. I had a heck of a hard time finding them all for my collection but they are worth looking for. If you were a fan of "Frog and Toad" by Arnold Lobel you can think of these as similar books for the slightly older crowd.
I had a chance to talk to Russell about the books and he loved doing them but was annoyed at how quickly several of them had gone out of print. I am a huge fan on anthropomorphic animal novels and I think his are some of the best. For a great read for yourself or a child over a week's worth of bed time reading, you can't go wrong with this series!
