Love and Other Unknown Variables by Shannon Lee Alexander (hardcover)

Charlie Hanson has a clear vision of his future. A senior at Brighton School of Mathematics and Science, he knows he'll graduate, go to MIT, and inevitably discover solutions to the universe's greatest unanswered questions. He's that smart. But Charlie's future blurs the moment he reaches out to touch the tattoo on a beautiful girl's neck.

The future has never seemed very kind to Charlotte Finch, so she's counting on the present. She's not impressed by the strange boy at the donut shop―until she learns he's a student at Brighton where her sister has just taken a job as the English teacher. With her encouragement, Charlie
orchestrates the most effective prank campaign in Brighton history…

Now Charlie is falling hard for Charlotte―and faster than 32 feet per second squared. Her gravitational pull is quickly becoming irresistible. But Charlotte has a few secrets of her own…and it’s only a matter of time before Charlie’s carefully-executed future comes crashing down.
