Twenty-nine-year-old Lucille "Lucy" Garnett is healing from a bad breakup the best way she knows how: volunteering at Adam Green Senior Center, writing blog posts about feelings she barely understands herself, and self-soothing with her analytical bestie, Moody. But when her ex-boyfriend Lonzo starts finding his way back into her safe spaces, Lucy realizes healing might not be enough. She needs a plan. Something visible. Something undeniable. Something that makes him see exactly what he fumbled. Then Jazz shows up: Mrs. Grace's fine grandson with a camera, a gym routine, and enough charm to be useful. Lucy isn't looking for love. She's trying to get sexier before thirty. But Jazz might make her forget who the plan was for.
