Eighteen-year-old Madeline Swan knows what it feels like to be invisible. While her younger sister Bella basked in their father Charlie's devotion, Maddy learned to exist in the margins-quiet, watchful, carrying a grief she never quite named. But when a personal tragedy forces her back to the rain-soaked town of Forks, she discovers that invisibility is no longer an option. Not when her sister has somehow become the center of attention for the town's most mesmerizing family. The Cullens are impossible to ignore: beautiful, graceful, and profoundly strange. While Bella falls under the spell of the enigmatic Edward, Maddy's gaze is drawn elsewhere-to his father. Dr. Carlisle Cullen is everything the rumors suggest and more-a portrait of ancient compassion wrapped in an impossibly youthful form. He moves through the world with the weight of centuries in his eyes, and when those eyes land on Maddy, they don't look through her. They see. The cracks she hides. The pain she carries. The woman she's trying to become. What begins as quiet conversations in the hospital emergency room-a sanctuary from Bella's increasingly bizarre romance-blossoms into something neither of them expected. Something neither of them can control. But Carlisle has spent three hundred years bound by a sacred covenant: to resist what he is, to live among humans without preying upon them, to protect his soul at all costs. Maddy is human, fragile, and already wounded. She should be off-limits. She should be forgotten. She is neither.
