George Egerton: Terra Incognitas is the first published work to focus solely on Egerton and her literary legacy. It covers the range and extent of Egerton's life and literary career from her emergence into the milieu of London publishing in 1893 to her dramatic works (both original and in translation) and their performance history into the 1920s. This work is an essential addition to ongoing recovery projects and is the first to focus on her 'lost' and unpublished works, mentorship of younger writers, her experiments with characterisations and themes, sociopolitical stances, innovations with form and content, and ultimately, her literary legacy. In doing so, George Egerton: Terra Incognitas reassesses Egerton's broader contribution to fin de siècle and early twentieth-century literature and drama and repositions her as among the most important of the literary innovators of period, and a noteworthy precursor to later female literary modernisers including Katherine Mansfield, Dorothy Richardson, Elizabeth Bowen and Virginia Woolf.
