Reviews of "Keeping Faith" are generally positive, with most reviewers having only minor complaints and a few not liking the book. Publishers Weekly notes previous readers of Jodi Picoult will not be disappointed with "Keeping Faith."
Publishers Weekly feels the heart of the book is the mother-daughter relationship of Mariah and Faith; a relationship made more complicated and powerful because of a custody battle. Multiple reviews on Amazon.com note the provocative nature of the book and that it makes them think about things such as religion. One Amazon.com reviewer states the book is causing her to lose faith in Jodi Picoult. As an avid fan, she feels the book is predictable and is missing trademark Picoult plot twists.
