Publishers Weekly has named E-mergency one of the best picture books of the year. This was a true collaboration, starting with Amy Krouse Rosenthal, who introduced me to Ezra Fields-Meyer and his video about a clumsy letter who falls off a roof. I also got loads of help from Victoria Rock, my editor at Chronicle, and Maria Walther, a fabulous first-grade teacher who helped me include lots of language lessons. And of course, I’m indebted to my wife Jan, who came up with some of the better gags, including the “E-book” announcement on the back cover. Thanks to all for making it happen.
