About the Book

Psyker Marine: Book 4 opens up the second half of the series. The fronts widen. So does the protagonist’s skill tree, which is starting to ask questions about itself.

Same tactical grammar, more strategic frame. The combat-LitRPG reader who’s been trained up by the first three books gets paid back here: every fight teaches something specific about the build, and the build is becoming unmistakably Thorne’s rather than the Aetherion’s.

Produced by Royal Guard.

For Readers Who…

are deep in the series and want the war to widen. Pace stays tight.

This is Book 4 of Psyker Marine. The series continues with Psyker Marine: Book 5.
