Just Finished, Few Things

Spoliers Below.... although I guess if your on this specific forum, reading about a book written in 2007 you've most likely read it....

anywho. I have done a little research in the Rant section. I read 2 of the longer threads going over how time travels is supposed to work in this book (some phillapino from earlier this year, good thread), and the thread he links to that seems to be the original "green / chet / rant are these guys doing these things". I'm all good and dandy with that.

so my questions:

Green is refered to as a Historian, is eluded to being immortal but obviously never kills irene. I understand his plan is to send chet or rant or both back to kill Irene to make the final "copy" the immortal one, but they both refuse and choose to help Irene instead. SO. Green was not successful in killing his mother, therefore is not an immortal based on the immortalizing process layed out in the book. Why is he still refered to as Historian?

If the origianl, significant account of time travel in the book is Green's acident with Eco's parents (a mistake), how did Green (or anyone for that matter) learn to time travel on purpose? I rememeber the details of Monk's and brainwave lengths, yadda yadda, but where do flaming cars come in? essentially i'm asking if I missed some explanation. If this is a "just go with it", i'm cool with that.

Now the real question I have is: Which of this awesome's dude's books should I read next? Just finished Rant, loved it. Before that I read Survivor, loved it. No desire to read Fight Club for now. I read a chapter or 2 of Pygmy (sp) and i'm not sure if I can get past the style. So which book next?

Thanks!
