I'm a big fan of Eric Carle but only just discovered this little gem! Through his books, he effortlessly communicates his own 'awe and wonder' of the world around us and allows us to share it with our children. My eldest started school this year and has recently done light as a topic - this book fitted beautifully and we were able to talk about all the different light sources the firefly encountered. Very cleverly written with two layers of text to explore; that of the narrator and the speach of the characters involved. Finally, there is the lovely surprise at the end; the flashing little lights of the fireflies. It's at this point that my own two boys race to switch the light off to get a better look - a wonderful bedtime story experience.
