here's a great tidbit my sister veronica sent me:
The Eggers book, an adult novel based on Maurice Sendak´s classic Where the Wild Things Are was actually acquired by Ecco last winter, but kept quiet until now. Foreign rights are in play at Frankfurt and Ecco publisher Dan Halpern is predicting, "I think it`s going to be his biggest book. I think it´s going to be huge." Ecco is publishing the book in fall 2008, to coincide with the Spike Jonze movie adaptation based on Sendak´s book, for which Eggers wrote the screenplay. (source unknown to boo)
