This is a stunning action filled sci-fi/space opera story. The worldbuilding is creative, the plot is exciting, the writing style is engaging and keeps you hooked, and the characters are great.
Captain Lee is strong, brave, and complex, but also has a vulnerability and trauma from her tragic past. She's also guarding a deadly secret in the form of 'MAC'. This reminded me of the dynamics and bond seen in Halo between Master Chief and Cortana.
It also has the same great vibes as 'Firefly' TV series, it's fast paced, lots of action, intriguing conspiracies, scientific enhancements, and the dynamics of a crew in space on a mission faced with challenges and threats.
I found this to be very immersive and I didn't want to put it down, and there were lots of secrets and plots twists. I'm invested in this series and can't wait for the next book!
