The upper world
(Book)

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.
