Work in Progress by Michelle Morgan

Publishing-house receptionist and aspiring writer Lindsey Deal spent her days dodging bullets: one insufferable boss, one sinister-looking spider, and, most daunting, a certain romance novel-in-progress that screamed to be finished.
The first two were easy enough. The third required…motivation.
Enter: Rian Harper. Mysterious. Cool. Sexy as sin. The rule-breaking, covered-in-tattoos musician may be just the motivation Lindsey needs to finish her manuscript—and test the limits of her comfort zone.
But he’s too old for her. Too afraid to open up. Too much her new boss.
Single dad, brooding artist, corrupter of women. What Rian Harper needs is a business partner, maybe a creative partner. Someone who can have his back. He doesn’t need her tempting him to fall in love. It could ruin them both—especially when the too-sweet, too-pure, too-young woman discovers his longest-held secret.
