Hello, can you steer me in the right direction of what my professor it looking for? We need to find a book and critique it on the subject of life coaching. Would any book by john c. maxwell work. thanks

Probably. Especially since others seem to refer to Maxwell's work and writing in their own life-coaching activities.
