I take it fantasy doesn't fit into this section....i can't remember the name of this book! My bro has it, its about a boy int he future whos a delivery boy with a ninja sword. It sound stupid but its accually a really good book. Its not a kiddy book either its like a grrrade 12 read. I'll get back to ya when i remember the name or find the book and get the name.
Well there seems to be two on this forum who like Asimov. I think his Robot Triolgy is by far the best. Unfortunately I have lost all of my Asimov books in one of my house moves. Gives me something diffinate to search for when I go to the bookstores,thrift stores and garage sales.
One I really liked is Star Trek: The Next Generation and X-Men: Planet X. A combination of my two favorite sci-fi groups. You'll just have to the the book. Don't want to spoil it.
Another good series is the Wheel of Time by Robert Jordan. Very nice fantasy series (of course I'm basing my assuption of how good the series is from the first book). I think there about 4 or 5 of them.
