From book cover:
Harte Schale, weicher Kern - das ist Ruder Montgomery. Der attraktive Bauunternehmer ist einer der begehrtesten Junggesellen der Stadt - die Frauen liegen ihm zu Füßen. Nur Hope Beaumont, die Direktorin seines Hotels, zeigt sich von ihm unbeeindruckt. Doch lange ist auch sie gegen Ryders rauen Charme nicht gefeit, und nach einem Kuss an Silvester knistert es gewaltig zwischen den beiden. Alles könnte so schön sein, doch als Hope von ihrer Vergangenheit eingeholt wird, wird die zarte Liebe auf eine harte Probe gestellt...

From goodreads.com:
Ryder is the hardest Montgomery brother to figure out - with a tough-as-nails outside and possibly nothing too soft underneath. He's surly and unsociable, but when he straps on a toolbelt, no woman can resist his sexy swagger. Except, apparently, Hope Beaumont, the innkeeper of his own Inn BoonsBoro...
As the former manager of a D.C. hotel, Hope is used to excitement and glamour, but that doesn't mean she can't appreciate the joys of small-town living. She's where she wants to be - except for in her love life. Her only interaction with the opposite sex has been sparring with the infuriating Ryder, who always seems to get under her skin. Still, no one can deny the electricity that crackles between them...a spark that ignited with a New Year's Eve kiss.
While the inn is running smoothly, thanks to Hope's experience and unerring instincts, her big-city past is about to make an unwelcome - and embarrassing - appearance. Seeing Hope vulnerable stirs up Ryder's emotions and makes him realize that while Hope may not be perfect, she just might be perfect for him...
