A Game of Thrones
A Clash of Kings
Jacks somehow survives the slaughter when Queen Cersei Lannister consolidates power following King Robert's death and he is imprisoned. He is later sent with Cleos Frey when he is returning Tyrion Lannister's counter terms and Eddard's bones to Robb Stark, the King in the North. He is then put under the command of Hallis Mollen.
A Storm of Swords
Jacks is sent north with Hallis Mollen's men to escort Lord Eddard's bones back to Winterfell. Before they reach Moat Cailin, however, the ironborn invade the North. The whereabouts of Hallis, Jacks, Quent, and Shadd are currently unknown.
