Perfectly aligned for readers of Ian M. Banks's The Culture series and Ursula K. Le Guin's "The Ones Who Walk Away from Omelas", The Sixth Nik is a galaxy spanning adventure from the New York Times bestselling author of Whalefall and Angel Down.

Deep into space, far past the triworld outposts, beyond range of the lethal trollbot internet, soars The Sickness: a ship woven from biomatter and capable of reacting to every need of its human crew. Sisilla, a nine-year-old cultist with a brain enhanced by arcane tech known as "niks," has boarded to investigate the enigma of Fém--a plague-riddled planet that has abruptly gone rogue. The mysterious crew includes a faceless assassin, a beautiful engineer jigsawed by plastic surgery, a peyote-addicted medic, and--most lethal of all--a rugged, NonModded captain with a score to settle with Sisilla. Other dangers abound. A hacked robot begins to believe Sisilla is its daughter. The Sickness itself is mutating, possibly even pregnant. And the secret of Fém is more horrific than anyone could have imagined. To survive, Sisilla will need to forsake her predetermined fate and embrace the unknown.
