I read loved all three black ocean series after getting hooked on the mobius oceans as author said it was basically his fanfic to firefly. Astral prime felt liked one great big mission rather than individual missions like the other two series. I really enjoyed astral prime series though i feel it dropped the ball a little on the final conflict and resolution (dont want to give away too much of the story). Also, I wish the ”background” antagonist was developed further with even more back story but I am greatful to the author for these three series they were a constant companion for me on the car.
