The Soulless

Author Jonas Saul (Sarah Roberts Series) and Rania Stone (What He Didn't Know) team up to write another dark thriller, The Soulless.
Despite dire warnings from renowned scientists, a dangerous experiment at the Large Hadron Collider in Cern received approval.
But something goes wrong.
An explosion in the particle accelerator creates a massive crater and opens a rift between the planes of existence, resurrecting good and evil souls alike.
Cassandra, a woman close to the explosion in Switzerland, finds her dead parents have been restored to life, while Mujtaba, a devout Muslim in the Middle East, is haunted by visions telling him what to do to save the world.
In cities thousands of miles apart, Cassandra and Mujtaba fight to correct the imbalance the particle accelerator created before it's too late and the entire Earth is devoured by a blackness unleashed from the Earth's core.
They soon learn that Hell is for the righteous among them.
