First Love, Second Draft by Becca Kinzer

She’s a romance writer burned out on love. He’s her famous baseball star ex-husband. The last man she wants to be forced to work with is the one who broke her heart.

Rom-com writer Gracie Parker hasn’t written a bestseller since she and her husband, a major league baseball star, divorced five years ago. On thin ice with her publisher—and with a looming deadline—Gracie couldn’t have picked a worse time for a painful injury that has her flat on her back. At this point, she’d accept help from anybody . . . except her first love and ex-husband, Noah Parker.
The baseball season has just ended in massive disappointment for Noah. He’s facing the stark reality that he gave up everything for a career that’s let him down and that it might be too late to get back the one person he should’ve held on to. So when Gracie’s nephew calls, saying Gracie’s looking for a tenant for her next-door rental, it feels like it’s meant to be.
All Gracie cares about is turning in her manuscript on time, which is directly at odds with Noah’s attempts to win her back, even if she is slightly charmed by his kindness. But can people ever really change? Then Noah throws a curveball that could give Gracie the extension she needs, but it will mean working directly with Noah, something she’s not sure she can face. With no other choice, and everything on the line, Gracie must decide if it is too late for a second draft of their own love story.
