The universal laws of Marco
(Book)

"With girlfriend Erika, a full-scholarship to college, and a busy life with his tribe of close friends, high school senior Marco Suarez holds tightly to his carefully choreographed life, until Sally, his first kiss, moves back to Miami." --,(Source of summary not specified)

In the summer before eighth grade, Marco Suarez kissed his best friend Sally Blake. This was his first spark. Whenever he's thought about that moment, he's traveled through a wormhole of sorts, reliving those brief seconds when his view of time distorted. At the end of that year she disappeared, and he never knew why. When Sally returns in their senior year, Marco is shaken. He has a girlfriend, Erika Richards. He's leaving at the end of the school year, on a full scholarship to college. He's busy with his friends and making money to help support his family. But he finds that a first spark is hard to ignore. -- adapted from jacket
