The Off-Limits Rule by Sarah Adams (Author)

Lucy Marshall has hit rock bottom. After failing to succeed as a single mom in Atlanta, she’s back home and moving in with her older brother, Drew. Reconnecting with her support system is the right thing to do, but Lucy can’t help but feel like a failure. Her four-year-old son deserves the world, and all she can give him is a spare bedroom. But Drew is the sweetest uncle, and some quality time might be exactly what they both need to start fresh. That is until she meets Cooper, her brother’s incredibly hot best friend.
