Malia needs to leave El Salvador. A surfer and aspiring engineer, she came to Central America as a Peace Corps volunteer and fell in love with Ben. Malia's past year has been perfect: her weeks spent building a much-needed aqueduct in the countryside, and her weekends spent with Ben, surfing point-breaks in the nearby port city of La Libertad. Suddenly, a major earthquake devastates the country and brings an abrupt end to her work. Ben and Malia decide to move on.

Now free of obligations, they have an old car, a wad of cash, surfboards, and rough plans for an epic trip through South America. Just as they're about to say goodbye to their gritty and beloved Salvadoran beach town, a mysterious American surfer known only as Pelochucho shows up-spouting grandiose plans and persuading them to stay.

Days become weeks; documents go missing; money gets tight. Suddenly, Ben and Malia can't leave. Caught between bizarre real estate offers, suspect drug deals, and internal jealousies, this unlikely band of surfers, aid-workers, and opportunists all struggle to find their way through a fallen world, in Kilometer 99 by Tyler McMahon.
