While Jaina and Wedge prepare to evacute Borleias, Luke takes a team to Vong-occupied Coruscant to eliminate a potential evil threat. This was an enjoyable novel in the moment, but I don't remember much. I did find the Coruscant bits with Luke, Mara, Tahiri and the Wraiths the more interesting half. (Note to self: I really need to review these in a timely manner.)
Enemy Lines II: Rebel Stand (Star Wars: The New Jedi Order, #12) by Aaron Allston This is an interesting conflict, with two adventures in one of the star wars series.
So the "Enemy Lines" duology was not my favorite of the NJO. I did enoy the stand at Borleias sequnces but the mission to Corusant felt shoe horned in and unecessary. Not that they were poorly written, they just felt out of place within the context of the story.
