Seven Rules for Breaking Hearts by Kristyn J Miller

Love breaks all the rules.

Margo Anderson is sworn off commitment. Alongside her best friend Jo, she runs a viral podcast featuring rules for hooking up without catching feelings. So when Jo surprises her by deciding to get married and takes up a sponsor's offer to host an all-expenses-paid wedding trip on Catalina Island, they have the whole internet to answer to.

In a scramble for content to appease their disappointed listeners, Margo cooks up a social experiment: break all her own dating rules, just to prove that it's a bad idea. And she's found the best man for the job in the groom's best friend and her old high school nemesis, Declan Walsh. He may be easier on the eyes than Margo remembered, but he's sure to be as smug and annoying as he was before. There is no chance Margo will ever catch feelings for him...until she does.

The more time they spend together through cake tastings and wedding party activities, Margo can't ignore their obvious spark, and she may actually be enjoying getting to know Declan. But can she let go of the rules to let him in?
