The second book in the Legacy of the Force series is Bloodlines by Karen Traviss. Sue Rostoni posted the info in her blog yesterday.
Legacy of the Force is the nine-book series that leads us into the ‘Legacy’ era, which takes place after the NJO and Dark Nest. We don’t know much about it, aside from what can be drawn from the titles, but we do know Boba Fett will be involved in (at least) Traviss’ portion. Check the coverage of the Legacy C3 Panel for more on ther series as a whole.
