I've had mixed feelings about this book and its author for quite a long time. How could something so innately intuitive come from someone so intolerant? Jay Lake had an insight that revealed it to me, though -- "the man who wrote that book so full of human understanding and real pain had long since turned into a very sad, vile person who worked very hard to do evil to many other people," he wrote. 
 Ender's Game remains a timeless and thoughtful insight into the nature of childhood and the isolation of intelligence, no matter the current nature of its author.
