When a mysterious tunnel in Central Park allows a heartbroken college dropout to revisit a tragic incident in her past, will she ever move on and embrace the hope**—and love—**in her present? This heart-wrenching coming-of-age romance is perfect for fans of Jandy Nelson and Dustin Thao. Tia Cruz Adlon is sleepwalking through life. Once an ambitious student, she’s now unable to move forward, dragging herself to her dog-walking job and dodging calls from her concerned parents. Until she follows the sound of a mysterious ringing bell to a tunnel in Central Park, a tunnel that can transport her back in time. Back to the summer of her first love, Natty Poole. Tia and Natty didn’t interact much during high school. But after awkward, MIT-bound Natty delivered the graduation speech of a lifetime, Tia couldn’t help but take notice. Despite their looming departures for college, they fell hard. But their perfect summer came to a tragic end, separating Tia and Natty seemingly forever. Every time Tia enters the tunnel in Central Park, she can revisit her summer with Natty, but Natty can’t see or hear her. Even so, Tia remains obsessed with finding a way to change the past—so obsessed she’s ignoring her present, which includes the handsome and persuasive film student Razor Ford, who is dead set on having Tia star in his student film. Every moment spent with Razor feels like a betrayal of Natty, but there’s something about Razor that keeps pulling her in. Torn between altering the past for Natty or embracing her future with Razor, how can Tia possibly move on when her heart and the tunnel won’t let her?
