Once there were four worlds, nestled like pages in a book, each pulsing with fantastical power and connected by a single city: London.

All her life, Olivia Prior has wondered who she truly is and where she belongs. Her only clue is a slim, battered journal. Her mother’s journal, full of entries that seem to show that she was unraveling and drawings that look like blots of ink… until Olivia notices a hand, a door, a bloom, a skull.

A masterful tale of ambition, jealousy, desire, and superpowers. Victor and Eli started out as college roommates - brilliant, arrogant, lonely boys who recognized the same sharpness and ambition in each other. In their senior year, a shared research interest in adrenaline, near-death experiences, and seemingly supernatural events reveals an intriguing possibility: that under the right conditions, someone could develop extraordinary abilities. But when their thesis moves from the academic to the experimental, things go horribly wrong.
