Lydia-Marie Prescott is like any other 17-year-old senior in high school: she's cramming for finals, staying up late finishing homework (often at the last minute) while still finding time to work on a novel. There's one key difference between her and the average senior, however: three weeks into the school year, she finds herself stuck in the hospital after being diagnosed with leukemia. Going from seeing friends almost every day at school to daily phone calls instead of face-to-face interaction becomes a substantial roadblock in her routine. After getting an intriguing letter from a boy in the hospital room across from her delivered with her meal, she begins to have hope (however crazy it sounds) that her days will become a little brighter. Will she eventually meet him face-to-face, or will their interactions be forever restricted to communication via letters? Read to find out.
