As the only woman coder at her firm, Lark is thrilled to land an account for a huge client. But her dream job quickly becomes a nightmare when she accidentally projects a scandalous (and completely unsolicited) picture from her phone onto the screen during a presentation. Before she can recover, her coworkers jump in to steal the account, leaving Lark jobless and broke.

When a friend suggests text message-based sex work as a stopgap between jobs, Lark is dubious. She's all about sex positivity, but carrying out sexual fantasies - even digitally and anonymously-with complete strangers is daunting. How will she explain how she's earning a living - especially to Toby, her good friend and long-time unrequited crush?

Still, she needs the money, and after a few (embarrassing and hilarious) attempts, she actually starts to like sexting - especially with one particularly charming and nerdy client who keeps popping up in her DMs. But as Lark and Toby grow closer, she finds herself with a decision to make: tell Toby she's a sex worker, and try to forget the anonymous client who has her struggling to separate work from real feelings, or keep the secrets that are piling up in her inbox.
