When famine, civil war, racial hatred, ethnic cleansing, the slave trade and religious intolerance combine forces as the backdrop for romance and redemption, you know you've got the makings of a page-turner. In the compelling When the Lion Roars, author DiAnn Mills uses the complex and under-reported Sudanese Civil War as a foil for the character journeys of three mule-headed revolutionaries a doctor from the American Midwest, an Arab Christian convert from the Sudanese royal family and a Southern Sudanese army colonel with independence on his mind. These three have little in common, other than a connection to the colonel's 16-year-old sister, Rachel. When she is kidnapped, they must overcome their mistrust and prejudice and learn to depend on each other if they want to see Rachel alive again. Mike Parker is a former pastor who writes from Murfreesboro, Tennessee.
