Blow Out the Moon (Little, Brown, 2004).

“I have read your book Blow Out the Moon so many times, and loved it every single time! You once came to my school... I was in 4th grade at the time and now I'm going into 7th grade and still reading over and over your book!” -- a reader

Blow Out the Moon was written in the early days of the Web and Libby first published it there, along with photographs of the boarding school, how to do many of the things the characters did (cat's cradle, songs, games), and stories they read and wrote.   Children read it and emailed Libby; a school district put the book and Web site on all the computers in their system; Yahooligans and others recommended it.

Libby didn't approach editors until she had a packet of emails from children and recommendations from schools and reviewers. Children's Literature called the novel “entirely refreshing” and the companion Web site “a delightful compilation.”
