Sounds like a plan : a novel
(Book)

"Jackson Jones and Mackenzie Cunningham have a lot in common. They are both hard-working private investigators with their own firms in Los Angeles, each happily single, and very good at their jobs. But when they're together, they are like oil and water. After they find themselves working the same missing persons case, the idea of collaborating seems about as likely as a blizzard in Beverly Hills. But once it's clear that they have been set up to take the fall for a murder, they have no choice but to join forces and make a plan that will expose the truth. Bickering their way from Century City to Malibu and beyond, they find it increasingly hard to deny the sparks flying between them. But with a small army of mercenaries in hot pursuit and a killer intent on covering his tracks, there's not a lot of time to sort through their complicated feelings. Told in alternating perspectives, this rollicking, romantic thrill ride makes for a swoon-worthy mystery"--,Provided by publisher.
