Valiant is proud to present an advance preview of Harbinger #18 from New York Times best-selling writer Joshua Dysart (Harbinger Wars) and all-star artists Barry Kitson (Amazing Spider-Man) and Riley Rossmo (Bedlam, Cowboy Ninja Viking)! The Renegades are about to find out that imagination can be a killer as "Perfect Day" barrels toward a psyche-shattering conclusion!

Nothing is what it seems when hyper-psychics go to war. Held hostage by the Harbinger Foundation and scattered across their own mental landscapes, each one of the remaining Renegades must quest to unite with the others or be lost forever inside themselves. It will take courage, strength, imagination and an unwavering belief in one another if they're going to discover the dark truth behind their Perfect Day.
