People We Meet on Vacation by Emily Henry

Poppy and Alex. Alex and Poppy. They have nothing in common. She’s a wild child; he wears khakis. She has insatiable wanderlust; he prefers to stay home with a book. And somehow, ever since a fateful car share home from college many years ago, they are the very best of friends. For most of the year they live far apart—she’s in New York City, and he’s in their small hometown—but every summer, for a decade, they have taken one glorious week of vacation together.

Until two years ago, when they ruined everything. They haven’t spoken since.

Poppy has everything she should want, but she’s stuck in a rut. When someone asks when she was last truly happy, she knows, without a doubt, it was on that ill-fated, final trip with Alex. And so, she decides to convince her best friend to take one more vacation together—lay everything on the table, make it all right. Miraculously, he agrees.

Now she has a week to fix everything. If only she can get around the one big truth that has always stood quietly in the middle of their seemingly perfect relationship. What could possibly go wrong?

The Ruins by Scott Smith

 

Trapped in the Mexican jungle, a group of friends stumble upon a creeping horror unlike anything they could ever imagine. Two young couples are on a lazy Mexican vacation–sun-drenched days, drunken nights, making friends with fellow tourists. When the brother of one of those friends disappears, they decide to venture into the jungle to look for him. What started out as a fun day-trip slowly spirals into a nightmare when they find an ancient ruins site . . . and the terrifying presence that lurks there.

Dumb college students, man vs. man and man vs. nature, slow burn terror. It was awesome.
