Margo Stuart and Teddy Atkins are well into their respective history and philosophy Doctorate studies at Oxford University when they stumble across a key left behind by a secret society called the House of Plato. Further investigation puts them on the radar of the Michellan Society, a murderous, rival society of the House of Plato. The two societies have been fighting for centuries to control the object of immortality and relics of Hell. Margo and Teddy must help the House of Plato find the missing pieces of the object of immortality while trying to figure out what the society truly wants the pieces for; to keep them safe or wield them.
