At the end of book one, Red Rising, Darrow's brutal experience at the Institute concluded with him firmly embedded in Gold society. Darrow, a lowly Red hidden with the ranks of Gold, was required to choose a patron to sponsor his future and he chose to become a Lancer for House Augustus. This means he now works for the ArchGoverner - the man who killed his wife. He did this in order to be close to his hated enemy as well as to be able to attend the Academy, where Gold prodigies learn starship fleet command. As a member of House Augustus, Darrow finds that life among the Peerless Scarred is not as straight forward as he hoped. It is often hard to tell the difference between his allies and his enemies which leaves Darrow pretty confused as to the best way to move forward with his hidden agenda.
