Perfect for fans of Neal Shusterman and Jason Reynolds, this powerhouse, mind-bending YA debut follows two teens, a generation apart, whose fates collide across time-and outside of it.
Today
During arguably the worst week of Esso's life, an accident knocks him into an incredible world-a place beyond space or time, where he can see glimpses of the past and future. But if what he sees there is true, he might not have much longer to live, unless he can use his new gift to change the course of history.
Tomorrow
Rhia's past is filled with questions, none of which she expects a new physics tutor to answer. But Dr. Esso's not here to help Rhia. He's here because he needs her help-to unravel a tragedy that happened fifteen years ago. One that holds the key not only to Rhia's past, but to a future worth fighting for.
Soon to be a major Netflix movie starring Oscar winner Daniel Kaluuya! (Get Out, Black Panther, Judas and the Black Messiah)

The electrifying sequel to the bestselling, critically acclaimed, page-turning thriller, The Upper World, soon to be a major movie starring Academy Award Winner Daniel Kaluuya.
With her mentor, Dr Esso, by her side, Peckham born and bred Rhia is beginning her first week at the University of Oxford. She's determined to have a fresh start and put the Upper World behind her. But fitting into the hallowed halls of Oxford proves more difficult than she thought when she struggles to find her people.
That's until Rhia receives a mysterious invite under her door to a secret and exclusive society called the Ravens. The Ravens are part of the 1% and being a member of the cult-like group guarantees students a life of wealth and success. But is Rhia really willing to sell out to secure her future?
And, more pressingly, with increasingly strange goings-on happening around her, could joining the group mean opening Pandora's box - and uncovering something even more mind-bending than the Upper World? Rhia is about to find out . . .
