Evidence from documents: Trouble Under Oz: '''''Trouble Under Oz''''' is a 2006 novel by Sherwood Smith, illustrated by William Stout and published by HarperCollins.
The Secret Order of the Gumm Street Girls: a children's novel written by Elise Primavera. The book was published by HarperCollins on October 1, 2006.
The Beatrice Letters: The book contains twelve punch-out letters (of the alphabet, as opposed to correspondence, although the ambiguity is intentional), and each is mentioned in different, interesting ways. An example is that the first letter is an E, juxtaposed against a card from Snicket to Beatrice, in which a map Snicket had drawn forms an E. The cardstock letters can appear to be anagrams of 'Beatrice Sank', Beatrice being the boat in the book ''The End'' and 'A Snicket Brae', as it has been said that Lemony Snicket lived in the hills for some time. The book also includes a poster of what appears to be the wreckage of 'The Beatrice', along with a cave, Klaus's glasses, Violet's hair ribbon, and Sunny's cookbooks.


Kidsreads.com praised ''The Beatrice Letters'', claiming "Snicket incorporates what could, surprisingly, be one of the most touching and heartfelt (if absurd) love letters ever written...it heightens the stakes, and the anticipation, for Snicket's eagerly awaited Book the Thirteenth."


Over 350,000 copies of the book were sold in the United States in 2006.
