If someone came up to me and said "describe the plot of Durarara" i probably would be able to do it in a concise manner or without spoiling anything...
So all i'll say is in Durarara!! Things happen and no one talks to each other unless it's in an anonymous chatroom.
Also Hot Pot... most important meal ever.
anyways Durarara!! the show is one of my fav Non-linear stories... i would actually argue that it is one of the best uses of non-linear storytelling considering how large the cast is.
Durarara!! the novel is a tiny bit more linear then the show considering the first volume only focuses on one arc, The Dollars... HOWEVER i have a feeling that the next volume will probably focus on the Slasher arc which happens somewhat simultaneously in the show... and the yellow scarves will probably follow after that which again... happens simultaneously... so as a whole i wont be surprised if these mostly non-linear stories end up being non-linear when they are all out.
Or it may not... i don't think vol 2 releases till november so it'll be a while before i know.
I really enjoyed the book but i would actually say watch the show first since the book adds so much more to what happens in the show... the book also spoils two things for the show in my opinion, one being an episode we dont see till late in season two and another being a character trait that is hidden but extremely important.
Plus this show has amazing music and animation and it's just a lot of fun.
I will say as far as how the light novel was written this is easily one of the most enjoyable reads. Either the authors style or the style of the translator (i don't know enough about how much the translator puts into these things if anything) or both is simply perfect, it's also a very quick read as most light novels tend to be but yeah i really enjoyed it and i'm sad i have to wait so long for the next one.
My fav part of the whole book is actually the afterword, he explains the title and i don't think i've laughed that hard in a long time.
I got the kindle version and it was about 7 dollars, the physical one goes for about 10, if you like the show give the book a read,
if you are curious about the show it's all on Crunchyroll. (they even have the dub if you prefer that)
And now Is it wrong to pick up girls in a dungeon vol 3 is out so that will probably be the next one i read... even though i have a huge pile of novels i want to get through.
