A good collection with 3 top notch stories and one that should have been developed a little better. The first two introduce Ender Wiggin's father as a child and college student and detail how Graff came to seek out Ender for Battle School. They also show Ender's parents' first meeting. The third is the classic tale which began it all, the original Ender's Game short story. The fourth followed 20 year old Ender to a distant world with Valentine but could have used a bit more development to make certain elements more believable. The set up was dynamic but the middle and end were not well developed enough. Still an excellent addition to the series overall.
