Slaughterhouse-Five

So far I am enjoying the outside reading book, Slaughterhouse-Five. I'm around page 90 in my reading and the plot is sort of beginning to straighten out. At first sometimes you couldn't even tell where they were or what they doing because the narrator was somewhat scattered. But now there is one narrator from what I can tell and his name is Billy Pilgrim. He might have a mental problem because right after a he was in a plane crash in which he was the only survivor he thinks he was abducted by aliens named Tralfamadorians. I think the book is written within a book, within a book? The setting in the book is confusing more than anything else. One character who is writing a book about Dresden, in which Pilgrim is in, skips from flashbacks to present tense to book scenes. So the time and place is always changing. I have read many war books before and not many relate to this book, but there is one that I've read, The Rifle, that relates because both skip around in the setting and both don't have one, set narrator. So far I think that I am doing a movie with Mathew Geisler and Josh Allen about the book. I think that we have to select a few parts, as opposed the whole book, to illustrate in the movie or else it might be too confusing.
