Isabel has one rule: no dating. She’s got issues. She’s got secrets. She’s got rheumatoid arthritis. But then she meets another sick kid. He’s got a chronic illness Isabel’s never heard of, something she can’t even pronounce. He understands what it means to be sick. He’s gorgeous, fun, and foul-mouthed. And totally into her. Isabel has one rule: no dating. But she might just consider breaking that rule for him.
