In honor of "Lost's" finale, I decided to highlight two favorite children's books that explore the idea of our humanity being interconnected. Unlike the show though, these books won't take you for a ride, don't involve a random tangent in time travel, and have an ending that is relevant to its beginning. :)
"Charlie Cooks Favorite Book", by Jula Donaldson. It's plot is basically a book inside a book inside a book, etc. and is written in a very playful, witty manner. The illustrations are quite clever and detailed. It's just a fun book to read.
I first discovered "Each Peach Pear Plum", by Janet and Allan Ahlberg, at a friend's house in their book basket, and I immediately fell in love with it. This is an interactive book that links a bunch of familiar nursery rhymes together in a game of "I spy", with characters hiding out on each page. The illustrations are very whimsical and fun.
