The Billionaire’s Single Mom by Leslie North

Billionaire lawyer Guillaume “Gui” Durand watched his two brothers fall for his grandfather’s thinly veiled matchmaking manipulations and he’s determined to not make the same mistake. Disguised as a “community project,” his grandfather has directed Gui to help struggling writer Riley Greene win custody of her niece and nephew. Seeing how his brothers fell for their community projects, he’s completely prepared to resist Riley’s considerable charms. Until Gui meets her. She’s open and warm, and for some reason, does things to his heart no other woman has.
Riley knows winning custody of her late sister’s twins is an uphill battle, but she’ll do anything to keep them away from their absentee father. Having a successful lawyer on her side is nice. Having feelings for said lawyer is not so nice. Resisting Gui is proving to be a challenge. From the minute she meets him, Riley is immediately aware of their red-hot chemistry. When they finally give in to their attraction, Riley has major doubts about getting involved with anyone when she has to focus on the twins. Unfortunately, going it alone has never seemed so lonely…
