This introduction provides an overview and brief history of New Thought and Christian Science in the late nineteenth and early twentieth centuries, particularly not only in America but also in Britain and Canada. The introduction also describes how popular literature written for and about children circa 1900 helped spread New Thought ideas while simultaneously critiquing them. As I explain, New Thought proved especially popular with female novelists and readers seeking escape from domestic duties and greater opportunities outside of the domestic sphere. Finally, the introduction includes a chapter breakdown outlining which works and concepts will be discussed later in the book.
