Among many types of life-writing genres that recently have not only become central to contemporary academic discourse, but also attracted wide readership, the biographical novel deserves special attention. Authors on Authors examines biographical-novel-about-a-writer--a sub-genre of biographical novel which takes a real writer and his/her life story as the subject matter for imaginative exploration. The study identifies all the major examples of the genre written in English between 1990 and 2010, while discussing a variety of approaches and methods used by contemporary authors in rewriting the lives of other authors. An original taxonomy of the genre based on Gerard Genette's Palimpsests is introduced in this work, following a claim that life and, consequently, life-writing are derivational practices and as such are inherently intertextual and ontologically palimpsestuous. Seen as the most representative and accomplished achievements of the genre, four specific attempts at a biographical-novel-about-a-writer (Author, Author by David Lodge, The Master by Colm Tóibín, The Hours by Michael Cunningham, and The Master of Petersburg by J.M. Coetzee) are singled out for an in-depth analysis in this multi-dimensional study which works dialectically across the borders of history, biography, literary criticism, philosophy, and textual analysis.
