Jessica Dettmann is an Australian author and performer.
In late 2018 her debut novel How to Be Second Best was published through HarperCollins, drawing comparisons to Liane Moriarty and Marian Keyes. The novel was endorsed by both Mia Freedman and Ben Elton, who labelled Dettmann “a fine comic writer”. The Daily Telegraph called it “the first book you have to read in the new year”.
