Alex Archer never really settled into life on Earth after being rescued from Scorpio, her former home that was occupied by the Lankies for the last 8 years. Her restlessness caused her to join the NAC Defense Corps and this book details her training and her first assignment, an emergency combat deployment. That's a rather ominous start to a military career for someone who spent years living in a bunker hiding from the Lankies, because even though she did not fit in on Earth, she has no desire to find herself back on a Lanky occupied world. But an allied warship has gone missing in the Alpha Corvi system and the NAC is deploying to investigate why. It's pretty obvious to Alex "why" - and her very first deployment has her heading right back into her worst nightmare.

I really enjoyed the Frontlines military sci-fi series and I was a bit sad when it came to a close. I commented in my review of the series finale that I hoped that the main story arc would be picked back up with a new generation of characters, since it was not resolved to my satisfaction. This book doesn't exactly extend the main story arc, but it does take place in the same universe and perhaps it sets the stage for exactly that. This is a story about Alex Archer, a dog handler on the planet Scorpio, which was taken over by the Lankies 8 years ago. Since then, the few remaining humans have lived underground, venturing out of their bunker only for scavenging runs to pick up supplies. These runs are extremely dangerous and their numbers continue to dwindle. Alex, and her dog Ash, accompany the military patrols on these runs because Ash is an early warning system capable of detecting Lankies before they can be seen. This book tells the tale of what might be the final scavenging run ever after it all goes catastrophically wrong...
