Star Wars: The Dark Nest Trilogy - Legends (abridged)

Luke Skywalker is worried: A handful of Jedi Knights, including his nephew and niece, Jaina and Jacen Solo, have disappeared into the Unknown Regions in response to a strange cry for help that only they could hear. Now the alien Chiss have angrily lodged a formal complaint, accusing the missing Jedi of meddling in a border dispute between the Chiss and an unidentified aggressor.
