Another lengthy one, but aren't they all?
Decimation: Son of M
So this book is way heavier than I expected. I was expecting a tale of desperation, but this...this is a whole new level of scumbaggery.
For those who don't know, this is a story about Quicksilver after the events of M-Day -- an event that wiped out most of the mutant race, leaving behind only 198 with their powers intact. Some died as a result of their power loss, however most just simply lost their powers. Quicksilver in particular is one of these mutants and boy, is he desperate to change that.
The book starts off with Quicksilver making his way through the day, simply attempting to go about his life. A shitty apartment in a shitty neighborhood, he's having a hard time functioning. To the point where he's even having difficulty buying groceries, which begs the question as to what he even does for money, but I digress. Eventually he gets the bright idea to use an old distress signal given to him by the Royal Family. During the time in which he's waiting -- revealed to be because Crystal had to debate with Medusa and Black Bolt in order to get permission to go -- he attempts to defend a still active mutant (who has a sarlaac pit in his chest for a power) from some muggers. Does not go well for him. Luckily Spider-Man shows up and beats them. He then proceeds to give Pietro a verbal beatdown die to the ending of the House of M since Peter had a perfect life with a wife and baby. It wasn't with Mary Jane, though, which is why he's so upset and on patrol. It's rough when your current wife wasn't your perfect fantasy wife in another reality #Marvelproblems.
Anyways, Peter basically maybe accidentally convinces Pietro to commit suicide. Peter attempts to save him, however Crystal shows up and takes Pietro to Attilan (since he is actually dying). At this point it's pretty much revealed that Pietro's plan was to attempt to go through Terrigenesis, which BB and Medusa refuse to allow. They explain that humans have never been allowed to do it, and that Inhumans are highly regulated due to the last time restrictions were lifted, some shit happened and the gene pool was severely damaged. So Quicksilver is allowed to remain in Attilan so long as he doesn't do dumb shit. Then he proceeds to do dumb shit by sneaking into the Terrigenesis chamber, undergoing Terrigenesis, and learning that he has time travel powers that also allowed him to create Speed For-I mean time doubles.
He uses this to steal crystals and convince Luna to come back to Earth with him, where he also has her go through Terrigenesis despite her being both too young and also half human. Luna gains the ability to see people's emotions via colors. It's found out that Quicksilver and Luna have to inhale the mists repeatedly in order to maintain their powers. Quicksilver uses his power to get some cash money (in a very smart way, I might add) and then goes to Genosha to restore powers to mutants. This bombs, however, because their abilities go out of control and Magneto basically hates Pietro even more now. The U.S. government and the Royal Family learn about this from Callisto being sent to a hospital by Magneto as a result of her restored powers going out of control and putting her into a coma. The Royal Family learns this info via the Fantastic Four.
Anyways, everybody goes to Genosha where it becomes a clusterfuck. Pietro and Luna (whose powers have developed into straight up empathy, being able to control people's emotion telepathically) escape with the T-Crystals via Lockjaw. However Pietro sends Luna back to her mother. Pietro didn't get all of the crystals, however, and the U.S. Government acquires them. Medusa and BB ask nicely for them back, however the government refuses, with BB giving a response: Blowing up all their forces and declaring war. The Royal Family gets one last piece of info from the FF, and then bids them farewell since BB's declaration means they can't be buds for awhile. The book ends with Pietro sitting in a room getting high on Terrigen and nothing else. He then leaves, deciding to become a walking source of T-Mists, restoring mutant powers; an idea that fucked everything to begin with.
So, this was a pretty good story. It really gets into not only the aftermath of the House of M, but also builds up to Silent War. A few things caused some questions: Why the hell can Pietro control his new powers so well, but the other mutants can't? He's not Inhuman. Luna makes sense since she's half Inhuman, but Pietro doesn't. Though, I suppose the anomaly could be written off as the result of the fairly recent retcon of him and Wanda being failed experiments of the High Evolutionary -- though that doesn't answer why M-Day affected him at all. Unless he has an X-gene as a result of the High Evolutionary's experiments as well? It might also explain how Pietro was affected so differently. The other mutants gained their powers with brutal side-effects, but Pietro got a brand new power set. Another question I have is when By Right of Birth takes place. It takes place before Atlantis Rising, since Medusa and Black Bolt are called out by Crystal saying, "If you had a child you'd understand," which doesn't make sense since Ahura has been born at this point. Atlantis Rising takes place well before this story, so what the fuck? It's still not understood as to when Attilan's society was completely rebuilt, either. The only answer is that some of the Inhumans went back to the moon, and that there was always the old Attilan that didn't go to Atlantis. This means that there's another Attilan floating around in space? Something is missing from the timeline, and it's bugging the shit out of me. One more nod to continuity before I wrap up is the inclusion of the Young Inhumans. Though, it's really only Jolen who has any actual involvement and just a mention of San, which bugs me because one of the covers consists of the Young Inhumans and Crystal confronting Pietro.
When all is said and done, it's a pretty good story that covers both the mutant after effects of M-Day and adds to the storyline of the Inhumans throughout Marvel. It has solid writing, though nothing to write home about in terms of dialogue. Roy Allen Martinez does a good job of conveying a lot of the emotional moments and powerful scenes that David Hine's writes however, which greatly helps. I can't really recommend this book to anyone unless you're interested in the aforementioned plot threads. Overall a good and enjoyable book, though I can't see myself revisitng unless I'm craving a good Inhumans or mutant story.
