Published in 1878, Roxy was one of Eggleston's best selling novels.  Its heroine, Roxy Adams, is a religious woman whose faith is sorely tested when her husband embarks on an affair that results in an illegitimate child. It is an example of pure American fiction; in a contemporary review, the New York Post wrote, "'Roxy' is the best product of Dr. Eggleston's activity in the field of fiction."
