In one impulsive moment the summer before they leave for college, overachievers Scarlett and David plunge into an irresistible swirl of romance, particle physics, and questionable decisions. Scarlett and David have known each other all their lives in small-town Graceville, Colorado, where David is just another mountain in the background, until, one day, he is suddenly so much more than part of the landscape. Magnetic, spontaneous, David is a gravitational force. And Scarlett, pragmatic, wry, eye on the future, welcomes the whirlwind he brings even as she resists it. Moving between the present and the past, this is the story of a seemingly grounded girl who's pulled into a lightning-strike romance with an electric-charged boy, and the enormity of the aftermath. Shana Youngdahl's debut explores grief, guilt, and reconciling who you think you need to be with the person you've been all along. It's an aching, transporting reminder that between the past that shapes us and the unknowable future, we have only the present to forgive ourselves and forge ahead.
