Stop Me if You've Heard This One by Kristen Arnett

Cherry Hendricks might be down on her luck, but she can write the book on what makes something funny: she's a professional clown who creates raucous, zany fun at gigs all over Orlando. Between clowning and her shifts at an aquarium store for extra cash, she's always hustling. Not to mention balancing her judgmental mother, her messy love life, and her equally messy community of fellow performers. Things start looking up when Cherry meets Margot the Magnificent - a much older lesbian magician - who seems to have worked out the lines between art, business and life, and has a slick, successful career to prove it. With Margot's mentorship and industry connections, Cherry is sure to take her art to the next level. Plus, Margot is sexy as hell. It's not long before Cherry must decide how much she's willing to risk for Margot and for her own explosive new act.
