Taking Care of Moses, by Barbara O'Conor, 2004

Someone left a baby on the steps of the Rock of Ages Baptist Church, and the whole town of Foley, South Carolina, is in an uproar about it. Nobody knows whose baby it is -- not childless Pastor Jennings and his wife Charlotte, who quickly "adopt" the baby; not Miss Freida the foster mother who's got a license to care for him. Only Randall Mackey knows. But he can't tell. And it's pretty much tearing him and Foley in two. A strong sense of place infuse the dialogue and conflict; Jaybird and Althea are literary siblings not soon forgotten. Strongly recommended.
