Written by Karen Traviss.
From Karen Traviss: "It's set just before the Yuuzhan Vong invasion, and answers a question that once troubled me: why did Fett side with the Vong, as he appears to do in the Star Wars Tales story Revenants, and then show up out of nowhere with a Mandalorian army in The Unifying Force and give the Vong a serious kicking? (And save Han Solo from them, too...)
This novella explains why. Because he is, after all, a practical man."
Originally only an ebook / e-novella.
At least one version of "Sacrifice" includes "A Practical Man" at the end.
"You can run," he said. "But you'll only die tired." — Boba Fett
