Identical twins, Today and Tomorrow Williams, share everything from their cascading auburn hair to their secret language until the autumn of their senior year at Holly Springs High.
After a homecoming dance gone wrong, Today's charismatic boyfriend corners Tomorrow in the shadowed quiet of his truck, leaving her with bruised wrists and a fractured spirit. His calculated lies paint Tomorrow as the aggressor, and Today-blinded by first love-chooses his version of truth.
Alone in her childhood bedroom, where matching twin beds now feel like distant shores, Tomorrow makes a silent promise to bury the truth deep beneath her shame, sacrificing her own healing to preserve her sister's happiness.
As seasons change and graduation approaches, Tomorrow finds unexpected solace in Caleb's patient friendship, but wonders if the scars she carries inside make her unworthy of the gentle way he looks at her across their shared lab table.
