Timeline: Rise of the Empire Era
From the publisher:
Boba Fett is dead, and whoever hired the hit squad had better run — as fast and as far as possible!
A mysterious avenger is on the trail of Boba Fett's killers. Connor Freeman — a clone relation to Fett — has been drawn into the whodunit. Freeman, who feels like he could use some protection himself, has been recruited against his will to find and protect a particular bounty hunter on a distant world ... in Mandalorian space!
