That Song in Patagonia by Kristy Tate

When Adrienne discovers her husband, Seb, has been unfaithful, the illusion of her perfect life is indelibly shattered and she flees.
Nick, a shop owner who suddenly finds himself the center of media attention, follows.

They both escape to Latin America for different reasons. Adrienne is tired turning a blind eye to her husband’s affairs. Nick trails after her, not only because he’s become an overnight YouTube sensation and he doesn’t know how to handle it, but also because he’s secretly been in love with Adrienne, his cousin’s wife, for years.

Two people with hurting hearts and unrealized dreams explore the streets of Buenos Aires and the South American countryside, and it changes them both forever. And what they find in each other is something that might just heal them both.
Armchair-travelers who love the gentle stories of Inglath Cooper and Debbie Macomber will enjoy this exploration of Latin American coupled with a sweet second-chance romance.
