3 stories in one; "Tiptree" does it best with short stories, in particular these are around the star rift. It concerns an interst in early life around the rift and the unsung heroes who helped to promote peace and technology in the right direction. The first story will capture you; it's the best in the book. Teenager takes her shuttle joyriding into history. The second one has a mild romance in it (whether this works in SF/F is still debatable) but the sci-fi in story 2 is remarkable. The third story shifts from one view point to another on what is going on and can get confusing; once you understand who's who and where, you have to finish the story to find out how "Tiptree" brings it all about so smoothly. Sweet. This was worth the initial purchase -- hope to share it with you.
Tiptree was way ahead of her time, and this book is more proof. It is actually several short stories all related to human - alien contact. Tiptree deftly flips viewpoints from human to alien to illustrate the universal fatal flaw of false superiority. Another great read from Tiptree.
