Øyvind quoted Night Angel Nemesis by Brent Weeks (The Kylar chronicles, #1)
She scoffs, amused. "Kylar, if you were going to retire, you'd've done it."
"You wouldn't have done that job at the Repha'im estate. Some of my best agents have been doing 'one last job' for me for twenty years, Kylar. ruth is, people like us don't get new jobs. We're lucky if we get new masters---a thousand time luckier that most if our new master as i man like Logan. No matter how you lie to yourself, you'll get pulled back into the life, and the longer you wait to do what you must, the more heartache and grief you'll cause everyone around you.
