There are 6 Starbender Book Collectibles in Prey. Finding all their locations unlocks the “Prism Master” trophy or achievement.
The first 5 books of the series can actually be found in multiple locations. They have 3 spawn points each. They will always be at all 3 points simultaneously (so it’s not random, they are always show up in each of the 3 spots). You only need to find each book once.
This video shows the easiest locations. Everything except for the 5th book can be found in the Crew Quarters. Book #6 only has one spawn point, it’s always in Alex Yu’s suite in the Crew Quarters.
They can be collected in any order you like. You can still go back during main mission “Before I Give You The Key” and free roam around the entire map. The video shows them in chronological story order so you can also collect them while playing through the main story.
In the game stats under “Data” > “Notes” you can track which ones you’ve already found.
