This continues Jedi Knight Kerra Holt's infiltration into the Sith forces with the aim of bringing the Sith down from the inside, except she's got wind of the fate of her parents and has gone on a slight detour to verify their whereabouts.
This was a bit of a mess, and the story could have been fleshed out a little.
Anyway, it's still better than book 1 and the artwork was pretty decent.
