Tipping the Waitress With Diamonds: Harlequin comics

Sienna knocked on the doors of her aunt's restaurant looking for advice. She’s been promoted at the restaurant where she works, but if she accepts, she’ll have to work with the head chef—her ex-fiancé. But her aunt doesn’t answer the door, Brett Cameron does. He was her first love and is now a famous chef. She blushes like a teenager when he greets her warmly tells her that he has come to try to help her aunt with the restaurant...and that he could use Sienna’s help.
