Tag Brewer, former chief medical officer and now captain of the SRES Argo, had assumed command of the research vessel following the loss of his commanding officer to a Drone Mech attack. His orders, also given by the loss of his commanding officer was to pick up an extraterrestrial anthropologist on one of Eta’s planets, Eta-Five, who’d been left there five years ago by the SRES Hanno. The anthropologist, Lieutenant Sofia Vasquez, had been studying the planet’s native biological lifeforms and whatever sentient species might be found there. In typical anthropologist form, she’d insisted on doing the mission solo to better immerse herself in the local population. Included in that population was a Free Mechanic crew hiding from the robot-like Drone Mechs whose minds had been usurped by a strange signal, turning them into slaves for their unknown Drone Masters.As the crew of the SRES Argo comes together, their mission now to find these strange Drone Masters and stop the mind control over the Drone Mechs. The amazing characters and awesome storyline are enhanced by the medical knowledge woven into the story. The author's medical skills and research are apparent in the story, but don't overwhelm the reader with esoterics. Really a complete and absolutely entertaining story, that demands your attention from the first page to the last. This is a great read, and now on to the third book in this trilogy.
