Ghosts

Quite a bit of time off between book 1 and 2 for me, having finished the first in November, but this one doesn't miss a beat. 
Went with the audio for this as well, and R.C. Bray does a fantastic job again. There's just something about listening to something so fast paced at a fast speed that gets the blood going. I actually listened to this on a long drive while my fiancée slept, and when she woke up, she got completely sucked in too. 
Hell Diver X is gone, and outside of a small prologue that takes place 2 years after book one, this novel is entirely 10 years after the fact. Michael, aka Tin, is now a young adult himself. He's also a rising Hell Diver. Captain Ash has officially been replaced by Jordan, however his paranoia and mistrust of those around him may lead him into issues. The Sirens aren't the only thing on the surface, and the action is nonstop. 
I was thinking about how you could possibly write more than one book (there's currently 10) with so many similar things needing to happen, but honestly, everything is happening so fast and relentlessly that you don't even notice. 
This is a crazy paced military / dystopian scifi. I will definitely have to continue my way through the series now. Personally a 5/5* again.
