The Sixty/Forty Rule

six-ty for-ty rule (noun): a deal you make with your pain-in-the-butt client, when hating him starts to feel a little too good.
Jude Holland has slogged it for years at a chance to land a coveted job designing the city's most breathtaking restaurants and nightclubs. And when a spot opens up on her firm's design team, her boss makes her a design Theo Jordan-the firm's biggest client-a new restaurant, convince him to renew his contract with the company, and the job is hers.
If only he'd play along.
Theo is infamous for three very specific he's a hot-shot young chef-turned-restaurateur, a thorn-in-your-side client, and the kind of attractive that makes you wonder which kind of psychedelics the great maker was taking, when he created him. Not that Jude notices. She's too busy sticking to the plan, and it helps that he's a total ass, anyway.
That is, until a steamy business trip leads to a very different deal between these enemies, who suddenly can't seem to keep their hands off each other. Sixty percent of the time, they'd indulge those funny, fluttering feelings that seem to manifest whenever they're together. The rest of the time? They'd be nothing but professional.
It doesn't take Theo long to realize that's easier said than done. But with a restaurant launch and a dream promotion on the line-not to mention a workplace rival hell-bent on ruining her career-Theo only has a handful of weeks to convince Jude to make that sixty percent full-time.

The Sixty/Forty Rule is a slow-burn, enemies-to-lovers workplace romance between a sunshine commercial designer and her grumpy client. It has a healthy dose of spice and a happily ever after. It is the first book in the Sunset Landing series of standalone reads.
