The Marquess and the Midwife — Alina K. Field

Once upon a time, the younger brother of a marquess fell in love with his sister's companion. He was sent off to war, and she was just sent off, and they both landed in very different worlds. Now Virgil Radcliffe has returned from his self-imposed exile on the Continent to take up his late brother's title and discover the whereabouts of the only woman he's ever loved. Abandoned by her lover and dismissed by her employer, Ameline Dawes has found a respectable identity as a Waterloo widow, a new life as a midwife, and a safe, secure home for her twin girls. Called to London at Christmas to attend her benefactress's lying-in, she finds herself confronted by an unexpected house guest--a man determined to woo her anew and win her again. But, is loving the new Marquess of Wallingford a mistake Ameline cannot afford to repeat?
