Titan. A genetically engineered warrior for whom going home means a death sentence... Commonwealth. A powerful politician chasing a legend from her family's past... Seryn. A young girl seeking adventure and hiding more power than even she knows... Collective. A synthetically augmented scientist whose singular nature makes him an exile... Representatives from each of humanity's four feuding factions, each offered the chance to see the legendary Book of Ascension-an ancient artefact rumoured to hold the key to immortality. The four form an uneasy alliance before discovering they have been misled: Before they can see the Book, they must find a mythical deity, protect the galaxy from an ancient evil-and save humanity's future.
