The Lost Ones — Kevin J. Anderson; Rebecca Moesta

JACEN and JAINA
When the Empire died, they were born--a new hope for the New Republic. The young twins of Han Solo and Princess Leia have grown strong with the Force, thwarting the evil Nolaa Tarkona and destroying the Emperor's plague. Now, with their friends Lowbacca the Wookiee and Tenel Ka, the future heroes of an already legendary saga continue their training.

During a break in training, Jacen and Jaina are reunited with their old friend Zekk, an orphan living in the streets on their home planet of Coruscant. Young, wild, and free, Zekk has never had a care in the world...until now. He sees the changes in his friends. Jacen and Jaina have learned so much, have grown in so many ways. Compared to them, he is only a lost little boy.

However, a powerful being has seen his potential. Someone who knows about shame and jealousy--and how to make use of them. Someone who knows that the dark side of the Force is especially attractive when you've got nothing to lose...
