A Proper Marriage (Vicar Humbley #1)
Debbie Raleigh

Adele Morrow lived an eccentric, free-spirited existence before her role as wife to a noted scholar forced her to conform to a life of dull duty and order. Outwardly the very model of propriety, she secretly longs to be carried off by a dashing rogue. . . . At first quite pleased with his quiet, unassuming wife, Adam Drake is now unhappy and bored. He realizes it's his turn to change - but the conservative scholar will need a great deal of tutoring to become a daring rake!
