The electrifying sequel to the bestselling, critically acclaimed, page-turning thriller, The Upper World. In The Mirror World, we return to Esso and Rhia's epic story as they learn more about The Upper World. Soon they discover they are not the only ones who can wield its power, and that danger is brewing . . .

With her mentor, Dr Esso, by her side, eighteen-year-old Rhia is determined to make her mark on the hallowed halls of Oxford University – and put the Upper World behind her.

But that’s all easier said than done when in her first week she overhears talk of the world ending. And when an invite drops under her door to a secret and exclusive society called the Ravens, Rhia must decide whether she’ll join the cult-like group to unearth the truth.

Can the Ravens provide answers about earth's impending doom? Or will joining the group open Pandora’s box? Rhia is about to find out . . .
