On a personal level, anyone who has stood a long watch will sympathize with the description of the time that Capt Krause spends on the bridge in this book. The cold, the boredom with the underlying tension, the inability to leave the bridge to make a head call - it all adds up. This is a superb story of sub vs destroyer combat and one that bears rereading.

This is the first book in the Ender series. I've read the sequels "Speaker for the Dead", "Xenocide", and "Children of the Mind" and this first book is by far the best. It's a little preachy at times, but overall a great story with an unexpected ending.
