The other half of the Book of Death is a series of "Fall" stories that tell the final fates of various Valiant heroes: 
 Bloodshot. Lemire gives us true scope, and rather delightfully puts Bloodshot into the roles of missing VH-1 heroes as he becomes Robot Fighter and Dinosaur Killer. But Bloodshot's final fall .. that's amazing, in parts shocking and tear wrenching [9/10]. 
 Ninjak. Despite its name, Kindt really gives us a final story for Unity, and it's a strong one, investigating the relationships between its three final members. This is a wonderfully somber character piece about legacies. There are also rather nice future connections to Rai. Unfortunately, it gets a little muddy in the last couple of pages [7+/10] 
 Harbinger. Dysart indeed gives us the endings for the entire Harbinger family, and those endings are meaningful and touching. The core story about Peter, meanwhile, is Dysart's science-fiction at its best. An appropriate ending for the series [7/10]. 
 X-O Manowar. The amazing thing about these "Fall" stories is that they aren't dystopias. They're inevitability full of hopes and possibilities and that may be the truest of X-O Manowar. Of all the Valiant comics, X-O focuses the most on legacies, so that's where this Fall comic goes as well. [8/10]. 
 The somewhat awkward part of this book is the question of its relevancy. If these deaths all happen within the chronology of the Book of Death future, then they're irrelevant, because that's theoretically averted. So what's the point of reading them? However if they're instead an alternative universe that's still the future of VH-E ... then why were they mashed up with the Book of Death crossover? 
 I suppose we should just appreciate these four stories on their own, because they're generally quite good.
