Nilsen wrote that Sparks now wanted to be seen as the author of the popular "Go Ask Alice" in order to promote additional books in the same vein that she had published or was planning to publish. (These books included "Jay's Journal", another alleged diary of a real teenager that Sparks was later accused of mostly authoring herself.) Nilsen concluded, "The question of how much of "Go Ask Alice" was written by the real Alice and how much by Beatrice Sparks can only be conjectured." Journalist Melissa Katsoulis, in her 2009 history of literary hoaxes "Telling Tales", wrote that Sparks was never able to substantiate her claim that "Go Ask Alice" was based on the real diary of a real girl and that copyright records continued to list her as the sole author of the work.
