Science Fiction is genre which makes readers and writers to look beyond the reasonable, shakes up our imagination and dream about future. Often some old sci-fi books are like prophecies. I've started reading sci-fi at age of 8-9, with greatest maestro Jules Verne, fallowed by Edgar Rice Burroughs and many others. In next 20+ years have read hundreds of different books, may be more. Here i want to share some of books iv'e read this year.

Old Man's War is about a soldier named John Perry who joins the Colonial Defense Forces who protect human interplanetary colonists. He is 75 years old when he joins military. Colonial Defense Forces give new body and new life to old people and for that they fight.

Blindsight - Peter Watts (2006)

It is suspected that the entire planet has been surveyed in one effective sweep. Humans finally know that we are not alone. The ship "Theseus" goes into space to establish contact with new civilization. But the reality turns out to be much more serious than any fantasies about extraterrestrial intelligence.
