A War of Gifts

A minor work in Card's Ender series, A War of Gifts takes place in the same time frame as Ender's Game and Ender's Shadow and would probably best be read near the same time as reading those two novels so that the Battle School culture is still fresh in the reader's mind.

Of the several Orson Scott Card novels I've read so far, this one is the least compelling, the least engaging. In fact, you can skip it and won't lose anything.
