On a doomed flight home from New York, Sean Allister is heading for a destination and a destiny far beyond his ordinary life.
Hell is breaking loose in Heaven and the consequences for humankind and angels could be catastrophic. With faith and hope at risk of being destroyed, it seems secrets, bureaucracy and fear are not the sole preserve of the living. With Sean, we see the return of the warm-hearted, whisky-swilling Crowley, now promoted to Spiritual Guide. Can this odd couple be the only hope to bring balance to Heaven and Earth as the battle for power drags them into a struggle that even the archangels are unprepared for?
