From Helen's Bookshelf in The Midwest Book Review

"Catholicism is as wide reaching as it is old.  "Critical Mass" is a series of short stories entwined around the traditions of Catholicism, with a focus on its weekly tradition of mass.  Centering on the perspective of four women over the course of a century, author Kathleen M. Henry spills a riveting commentary ont he nature of the church and its problems.  Critical and intriguing, "Critical Mass' is well worth the read for any fiction reader who likes a message with [his or her] story."
