I like Wolverine, but I'm not a huge fan. Mostly because he is cool, but he's basically a blunt instrument... he's not the one you call if you have a puzzle or a delicate matter to resolve. He might try to be sneaky, but he's most valuable when he's just blazing in, claws out, healing factor up, to take out all the bad guys. As he says, "he's the best he is at what he does, but what he does isn't very nice."
So, if you are a Wolverine fan, and you're just looking for him to just do what he does, you'll probably like this book. The plot is pretty straightforward; it's a solo Wolverine adventure, and no other X-men characters appear except for a brief conversation with Professor X. Wolverine is recruited by a former comrade from his samurai training days to pay back a debt by reclaiming a stolen item. This item is a drug, supposedly designed to cure all diseases, but which is deadly addictive, rendering anyone who takes it permanently healthy, but also essentially a slave of the drugdealer. The majority of this story is Wolverine goes to a place, finds one small piece of information, claws his way out, and gets back on the plan. Repeat about 3 times. But, like I said, if you enjoy that side of Wolverine, you'll get plenty of fight scenes here. You'll even get more than one fight with Silver Samurai, who also shows up.
But, as a book, I found it rather repetitive and boring. The plot repeats itself. It doesn't feel like it really solves any problems by the end. We're left where we started, with little to no progression in the characters or the world. Granted, that's kind of par for the course when it comes to superheroes, but this is a novel, not a comic book, so I guess I expect a bit more. The fight scenes are well thought-out, but the author has a tendency to over-explain simple things, including very detailed descriptions of mundane things such as putting on clothes or eating pancakes. It got kind of annoying.
Wolverine is written as he usually would be, but the other characters are pretty flat and boring. I could barely remember their names, and they were really just around to provide background for discussions, be plot devices, or at times be threatened so that Wolverine must strain himself to save them. Other than that, nothing special.
So, if you are looking for a basic book where Wolverine slices and dices, here you go. Otherwise, it's not that great of a read.
