Valentine's Day is among our most popular holidays, But what do the words "Be my valentine" mean? Who was Valentine? We know he lived in third-century Rome, during the reign of Claudius II. We know that he was a Christian priest... Ann Tompert beautifully weaves together the most enduing stories of Valentine to create a tapestry of the saint's life, while Kestutis Kasparivicius's illustrations take the reader back to ancient Rome. Together, author and illustrator pierce the historical fog that surrounds Saint Valentine to offer a glimpse of the man whose life remains a mystery.
