And Then He Kissed Me by Melinda Curtis

The chocolate wars…
Botanist Dr. Aubrey Summer has two goals for her trip to Ecuador – fulfill her bridesmaid duties and confront billionaire Marcos Alfaro about his efforts to steal her work. The wedding is being held at a hotel owned by Marcos and he’s rumored to be a guest. But along the way, Aubrey is distracted by a handsome man named Nino, a former employee with a crush, and Grandma Dotty, who’s got romance on her bucket list.
More at stake…
Marcos “Nino” Alfaro didn’t accumulate his wealth playing by the rules. Yes, he hired Dr. Summer’s assistant, but the principled young man won’t divulge the secrets to growing a richer strain of cocoa. When Nino meets Dr. Summer, it’s clear what he needs to do – use romance to learn more about her research. After all, he’s got to turn around the chocolate company he just purchased. There are millions at stake, not to mention his pride and – surprisingly – his heart.
Can he pass The Kissing Test?
