Under The Wishing Star

Description for UNDER THE WISHING STAR by Diane Farr:

Malcolm Chase's fortunate chance encounter with a kind young neighbor, Natalie Whittaker, gives the recent widower reason to fire his daughter's cruel governess and hire Natalie instead.

With her household duties usurped by her brother's new wife, Natalie longs to accept Malcolm's offer. But it would be unseemly for a woman of her station to move into a bachelor's household. Though the obvious solution is to marry, Natalie desires a union of love, not convenience--a wish that just might come true when fate gives her feminine wiles a fighting chance...

This is #1 in Whittaker Family Series.
