She created a beautiful world. Now he wants it all.

On her way to a speaking engagement, bestselling novelist Eli Grey gets into a cab and accepts a drink from the driver, trusting everything is fine. She wakes up chained in the stranger's basement. With no close family or friends expecting her to check in, Eli knows she needs to save herself. She soon realises that her abduction wasn't random, and though she thinks she might recognise her captor, she can't figure out what he wants. Her only clues are that he's very familiar with her books and deeply invested in the fantastical world she creates. What follows is a test of wills as Eli pits herself against a man who believes she owes him everything — and is determined to take it from her.

Terrifying and timely, set against the backdrop of convention culture and the #MeToo reckoning, Number One Fan unflinchingly examines the tension between creator and work, fandom and source material, and the rage of fans who feel they own fiction.
