January Winter's hopes of entering one of her homemade ice cream flavors into New England's 1st Annual Contest are dashed when she realizes she has no way of getting there - until she convinces her stoic coworker, Wyatt, to teach her how to drive.

Seventeen-year-old Daniel 'Red' Romero is actually four - he was born on February 29th. Red's never met anyone else born on a leap day, but he doubts that any others would be anything like him, with his shock of electric red hair and mysterious ability to camouflage into any background. That is, until Flynn Woodley appears in his life, moving into the apartment on the next floor along with his younger brother Tobias - and seemingly no parents. Tobias was born exactly four years after Red, and with his unnaturally blue eyes, power to predict the events of the future, and strange belief that the world they live in only exists in a novel, he is anything but ordinary. As Red grows closer to the Woodley siblings, he learns more about the secrets they're keeping, his unexplained connection to them, and the true magic that comes from a shared moment in time.
