Some of the other reviewers apparently neglected to read the book description ("Two complete novels and a short novel in one large volume"!), and gave the work a poor review on the basis of their own negligence because it wasn't new material. No, it is *not* new material, but this is not a new thing for the Vorkosigan series. This title is, in fact, the fifth Vorkosigan Universe omnibus (after Vorkosigan's Game; Young Miles; Miles, Mystery and Mayhem; and Miles Errant-- Miles in Love comes after this one). It packs all the Quaddie stories in one neat little volume: the Nebula Award-winning Falling Free, which is set 300 years P.M. (pre-Miles) and provides some fascinating background on how the universe that Miles knows came to be that way; the short story "Labyrinth," which is Miles' first contact with a living, breathing Quaddie; and the novel Diplomatic Immunity, which brings Miles and his new wife back to Quaddiespace, where it all began.
These stories include some of the best and most sensitive writing in the whole series, in my opinion, and I love the omnibus format. Not only does it save me a bit of shelf space (that is, if I can bear to toss my original copies), but it puts things together thematically-- we get the *whole* Quaddie story in one volume now, and it's much easier to see the connections between the beginning and ending novels. I adore Bujold's Miles books, and I wish she'd write more of them, too, but meanwhile, I'm happy to have the omnibus editions.
