Dark Nest Trilogy
From Wookieepedia, the Star Wars wiki.
The Dark Nest Trilogy is a series of novels written by Troy Denning. They take place 35-36 ABY. The novels detail how Luke Skywalker and his New Jedi Order confront the mysterious insectoid Killiks, who are a hive-minded species intent on conquering the galaxy. One sub-plot is the Skywalker family finding information on their ancestor, Padmé Amidala. Another sub-plot is the capture of Jaina Solo and Zekk.
Despite being a trilogy, the Dark Nest series followed the trend set in the New Jedi Order by having several character deaths in just three books, these included Lomi Plo and Welk who featured in Star By Star and Sien Sovv who featured a lot during the New Jedi Order series.
The Science Fiction book club released an edition of the Dark Nest trilogy in omnibus hardcover.
