In the novels of three early twentieth century English women writers—Evelyn Underhill, May Sinclair and Mary Webb—Thrall finds similarities and divergences in their various attempts to refute the notion that mysticism has no place in secular and rational modernity. Underhill defends a heroic mysticism, and Sinclair and Webb an erotic and natural mysticism, respectively. As such, they are pioneers of a "New Mysticism." All three focus on the authority of individual experience, the importance of psychology, the primacy of the life force, and the necessity of ethical purpose. Thrall is ploughing new terrain, the fruit of which will be of interest to historians, biographers, scholars of religious thought and of gender studies. Thrall's deep research and clear and accessible writing make Mystic Moderns an important and provocative contribution.
