A very fun novel version of a Marvel crossover event that Smith managed to make flow with action yet always focused on the not quite so black and white characters in this story. I really enjoyed it

Thank you to Titan for sending me this book for an honest review.

Overall this was a fun installment and a first marvel novel for me. I enjoyed reading about some of my favourite characters in a fast paced murder mystery. I felt like we got to see a different side to them from what we see on TV. I believe there are some historical differences between the comic characters in this story vs. their personas on TV which has accounted for this and it did make it quite enjoyable.

I felt a little confused at the beginning as I had no idea what to expect or if I should know about certain things going on and certain places but I felt this was easier to follow once the story really kicked off.

Hopefully I get a chance to read a few others in the Marvel universe! It's nice to see some different stories, worldbuilding and characters I've not encountered before.

I enjoyed this novelization of the core series of this Marvel "event." I'm not sure how much of this event really matters anymore in the Marvel Comics U, but that is neither here nor there. In terms of the novelization, I thought the author did a great job of capturing the mindsets, attitudes, and character of the characters from the story. He also did an impressive job of expanding upon and even building the characters in the book; something that is always difficult to do in a novel based on comic book characters and all of the retcons that take place. It moved at a fast pace; it held my interest throughout; and it helped enlighten me on some events that occurred in the limited series that I wondered about.

One thing that really surprised me was how much the author "humanized" Frank Castle aka the Punisher while showing how hyp0critical the other heroes could be at times. I thought this was really amazing, to be honest, 'cuz of how Castle tends to be portrayed in the comics. I especially liked the "idea" of how Castle is what you get when the heroes screw up so badly that somebody like the Punisher is needed to clean up their mess. Castle was well-written in this book and definitely a "highlight."

The book describes a lot of retcons that take place where events are created to create "secret sins" that everybody is keeping from each other. One of these days I will order the Original Sin Companion Omnibus and read those to find out what all of these "secret sins" truly are. The ones that are revealed are interesting, however (even though there is no resolution or whatever to the sins revealed in the book).

The "team-ups" in the story were fun in that it was an interesting mix of characters who are sent out to perform the secret investigations into why the Watcher was killed. Dr. Strange and Frank Castle. Gamora, Bucky, and Moon Knight. Black Panther, Ant-Man (Scott Lang), and Emma Frost. I think the best parts about the descriptions of each team's experiences was that the book went into more detail as to what was going on - what they were looking at, what they discovered, and what their thoughts and emotions were at the time. I realize a lot of this is probably pure conjecture on the part of the author, but he did a great job with the internal thoughts and emotions and interpersonal relationships that were going on with each team.

Dr. Strange is as arrogant as ever, and that arrogance really comes across in the story. So the author did a great job capturing this aspect about this hero was well. Captain America comes across as . . . I don't know . . . naively ignorant? Perhaps he expected too much out of each of the heroes he worked with, be they members of the Avengers or not? I still think it was crap that Thor could no longer wield Mjollnir for a period of time following this series, and the book sadly does not explain why Thor cannot hold his hammer, how he "lost his worthiness" while facing off against Nick Fury. At this point, I don't think what Nick whispered to him really matters in terms of it needing to be hidden in the novel, but whatever. Granted, Thor's intelligence, strength, and power levels are always all over the place it seems like, and that holds true in this storyline. He is only as intelligent as he needs to be, never mind he is how many thousands of years old and has more experience than anybody else on the team, and he is only as strong as he needs to be for Nick Fury to be able to stand against him and "win" (or fight Thor to a somewhat of a standstill, which is still a win for Nick). I don't believe Nick should have been able to stand against Thor, but neither do I believe that the Hulk is truly "the strongest there is" and should be able to stand against various gods and celestial beings and universal beings like he has and survive to tell the tale. Emma Frost was fun in the book; I'm still not really sure why she was chosen or how much of an impact she had in the book, but she was still a fun character to use and was a nice foil against Black Panther and Ant-Man. Black Panther was as mysterious as ever; his intelligence and wealth hinted at in the book as well as Wakanda's wealth, power, and advanced technology. So that was nicely done.



It was a fun book to read. I think the author did an excellent job expanding upon the story told in the limited series "event", and I also think the author did a great job of developing the characters of several if not most of the characters in the book. It is a good size cast of characters, and he handled them rather well (granted, he was using the storyline in the comics, so that helped him balance things out for the characters); I felt like he took what was done in the comics and actually improved upon it in his novelization.



And the cover is beautiful. I loved it. I think it's actually the cover of one of the issues in the series, but I still love it as a cover of the book. So, yeah, I am happy I picked it up and read it. It was well-done in my opinion; I would have said maybe not quite five stars but definitely four stars. However, the concept behind the story is not well thought out or executed very well in terms of sixty years of Marvel comics lore/history, so I am tempted to drop it down to three stars. However, the author did such an excellent job of capturing the characters in written form as well as in describing different events/moments in the book (AND making both the altered Mindless Ones AND Frank Castle sympathetic characters!!!!!!) (and the fact that the story is not his story; he merely made an existing story better) encourages me to leave it as four stars.

Marvel Novels are hit or miss for me. Currently I'm playing Marvel Snap so I have a renewed interest in all the characters as many of them I have no idea their story. This story has many many characters which I also am not a fan of, but this was a good book. The story was like a murder mystery and changes the path of the marvel universe. (at least what I know of it) i'm curious if this is cannon or just a story. enjoyable read for sure.

Prose novel adaptations of existing comic stories are a strange thing. The story already exists in one medium already, and whilst you often get novelisations of films or games, to get one of another type of book is probably rarer, and getting one that works well seems to be even more rare.

Comics aren’t just a medium, they have their own styles, their own methods of storytelling that work because of the medium they’re in. If you copy across that story as-is into prose the difference in mediums can quickly cause the story to break down. You have to make sure to get the right writer for the job. Luckily, Titan Books’ latest Marvel prose novel, Original Sin, not only gets this right, but manages to make the prose novel a lot more enjoyable than the comic version.

Original Sin begins by taking the reader to an ancient alien city on the Moon, where a powerful entity known as The Watcher makes his home. As the Watcher, who can see everything, goes into a state that makes him essentially shut down for several minutes, two mysterious figures break into his home and do something. After this, we jump forward a few years to join Nick Fury, Captain America, Black Widow, and Wolverine as they meet up for ‘meat night’ and decent steaks. When Cap gets a call from Thor about an emergency on the moon, the four of them head out; with the retired Fury being brought along for his expert opinion. Arriving on the moon, the group discover the body of The Watcher. Shot in the head, and with his eyes cut out, the powerful entity has been murdered.

Thus begins a murder mystery investigation as the Avengers, with the help of Fury, try to figure out who, or what, could be powerful enough to kill The Watcher. The investigation will lead them into conflict with several villains, and will lead to some dark secrets being revealed. But as the heroes try to solve the case, a mysterious figure approaches several others, including Emma Frost of the X-Men, Black Panther, Doctor Strange, and the Punisher, and sends them on secret missions that start to reveal pieces of the puzzle. But who’s behind it all, and why are they sending these heroes on these weird missions?

Original Sin was an eight-part story (kind of) that was published in 2014 by Marvel Comics that featured several big-name heroes that are brought together to solve the murder of a character that by their very nature should never be able to be killed. Even though this was after my time working in a comic book shop, this was a big enough deal that I heard about it when not following Marvel anymore. It was a story that had people intrigued just by the concept, and this is something that Smith brings to this novel in spades.

This book doesn’t read like a comic-book adaptation, it reads like a mystery novel. Instead of cops or private detectives though, it’s super-soldiers, mutants, and vigilantes who are looking into things. There’s also a big feeling of espionage and spy thriller that creeps its way into the book as things progress, especially when the identity of the person pulling the strings becomes known. And having read a lot of comic adaptations where the writer simply takes the events and translates them without changing things up much, this new approach works a lot better. Nothing is dropped from the story, no big beats are changed, but Smith is able to make it feel fresh and interesting in ways the original just wasn’t.

One of the issues I had with the original was the art. The book was very dark visually, and it often took me out of the story and made everything feel dark and depressing. It felt like the comic was trying to push the idea that this was a grim, ‘adult’ story by reflecting it in the art, but here Smith simply tells the story, gives the characters room to exist and feel real, and because he’s not pushing it to be gritty or grim it works so much better. It’s still a darker story than some would expect from superhero comics, but it doesn’t feel like it’s trying as hard, and it makes for a much more enjoyable read.

One thing I do feel I need to talk about for a moment is the cover. I know you’re not supposed to judge books by their covers, and in this case I’d push that saying even more. The first thing is that the cover has taken a cover from the comics and used it here. Which is all well and good, except the cover isn’t from Original Sin, it’s from Original Sins. Might not sound too different, but the latter is a series of one-shot comics that featured other characters. As such, of the 16 characters on the cover, only 7 appear in this story, and even then, two of them are barely there and one doesn’t even say a single word. The cover also seems to have been blown up a bit, and the more you look at it the more you realise it’s actually quite pixelated, and lacks detail. So if you’re looking at the cover, and either being put off, or expecting Ms Marvel to show up, please just discount that altogether.

Overall, this is one of the better comic adaptations I’ve read, and ended up being a really well put together mystery story. The characters were written well, the bombastic comic book moments didn’t feel weird or out of place, and Smith translated the plot into an enjoyable experience. Even if you’re not a big comic reader I suspect that you could pick this book up and have a very good time with it.

I read the comic book version of this and wanted to follow up with the prose novel. I frankly didn’t care all that much for this (or really for that). The essential idea sounds great — someone kills the Watcher?!? — and then these big secrets are revealed?!? — but the second idea wasn’t really developed well, and the mystery of who killed Uatu was not very interesting.

Read the audio version. This was a weird event. N. Fury wants to retire and somehow thinks a very complex plan involving tons of heroes risking their lives is the best way to go about it. I honestly did not follow all the logic steps of this master plan and the other bad person is what i consider a C-lister baddie. Maybe it reads better in full comic form.

This novel, set in the Marvel Universe, depends on a gimmick and a retcon. I thought the gimmick worked great--the Watcher has been murdered. I thought the retcon involving Nick Fury failed completely as most of the things that have filled the pages of Marvel Comics for decades would not have happened if it were true.

But the use that is found for the dead Watcher’s eyes was intriguing...

there was definitely potential here, but it felt like they consistently fell just short of making it properly work. murder mystery is a fun format for marvel, I just wish it had been written a bit better

3.5 rounded up. A lot of aspects of this were great -- I am impressed by how much latitude the author read given to add interiority to the characters that wasn't in the original comics format, in particular -- but just like the comics version, it could be 2/3 its length and be just as, if not more, thrilling and world-shaping and explosive, etc. The last two hours of the audiobook in particular really drag because the meat of the mystery has been solved and an extended fight sequence just doesn't work in book format. Also, wow, comics Fury is a straight-up monster. However, I love Steve, and also I love Rocket. I could see an adaptation of this to What If? season 2 or 3 being really cool because of the limitations of characters available -- there are definitely characters included in this novelization who could have easily been left out since their roles were relegated in the comics to mini-series runs outside of the main event (Thor, F4, Spider-Man, Hulk and Iron Man, Wolverine, Natasha...). The delineations between "morally pure" heroes and "pragmatic" heroes made for some interesting character team-up dynamics -- The Punisher with Doctor Strange in particular -- but it feels... Like tarnishing the whole idea of superheroes to have this "man on the wall" Space Genocides Are Okay thing going on in the background of heroic reactions on earth. You know? They're the Avengers, not the Prevengers, to quote MCU Tony, but he's right (that one time) and it's a more defensible moral and ethical stand for HEROES to take. I get that this is trying to be gritty and grounded in a form of realism, but like, I don't want that from superheroes. I want good guys. Hence loving Steve.

This book started out great, I thought it was a 4-5 star book with the various characters in unique teams. But I quickly realized that any suspense in the beginning was simply contrived by the author. Most of the characters knew what was going on or who they were talking too...but this information was withheld from the reader. So it wasn't exactly a mystery, just lack of information. Then the story seemed to grind to a stop somewhere near the middle. Then it just got tedious...I just wanted it to end.
Slight spoiler: Its one of those comic book stories that makes you think "if this power was available for as long as we are told it was, how is Earth ever in trouble? Any threat that is 50/50 to defeat Avengers, would be destroyed if this power joined and supported the Avengers."
