The bestselling, critically acclaimed novel of cursed books, quantum physics and the power of love

'Ingenious and original' Philip Pullman

If you knew a book was cursed, would you still read it?

When Ariel Manto uncovers a copy of The End of Mr. Y in a second-hand bookshop, she can't believe her eyes. She knows enough about its author, the outlandish Victorian scientist Thomas Lumas, to know that copies are exceedingly rare. And, some say, cursed.

With Mr. Y under her arm, Ariel finds herself thrust into a thrilling adventure of love, sex, death and time-travel.

Mindboggling, brainy and playful
