Query: Perfect Science Fiction

Robert Sawyer's books to me are perfect science fiction. He takes a simple premise, peoples it with wonderfully human characters, gets you emotionally involved with them, and then takes you on a wonderful adventure that challenges your beliefs and expands your mind. Again, I must repeat, I think his books are perfect, all of them, and this one, "Flash Forward," is my absolute favorite. Thank you Robert Sawyer for being such a brilliant author. I eagerly await each new book you produce.Arzani Burman, author of "The Legacy of Violetta Rose: An Inter-Dimensional Journey Through the Lincoln Tunnel and Beyond"The Legacy of Violetta Rose: An Inter-Dimensional Journey Through the Lincoln Tunnel and Beyond
