good book on the 1907 korean revival

hey guys, so i've been reading "to the golden shore: the life of adoniram judson" by courtney anderson (which i would highly highly recommend for all of you to ready it) and was wondering if there was a book similar to it but relating to the korean revival and horace underwood. thanks in advance for your suggestions =)

"When the Spirit's Fire Swept Korea"-by Jonathan Goforth is about the Korean revival. unfortuanatly I do not know of any books about Horace Underwood.
