""Jinks turns medieval history into fodder for both high comedy and allegory,"" said PW in a starred review of her Pagan's Crusade, the first of a planned quartet of books. Pagan's Vows by Catherine Jinks, the third installment, finds Lord Roland and Pagan renouncing their violent ways as they aspire to become monks at the Abbey of Saint Martin. Pagan's familiar, wry observations make light of his and Roland's struggles, adjusting to their monastic life. Pagan also finds out who is embezzling money from the abbey. (Sept.) .
