About this listen

When the aliens evolve, so does the threat against humanity in this thrilling sequel to Scorpio that finds Alex Archer in an epic battle of survival against the odds and the alien invaders.

Alex Archer is a soldier now, the only civilian survivor from Scorpio to join the NAC Defense Corps. With their training complete, Alex and her friend Private Isa Cressey find themselves on emergency combat deployment with their new unit. The destination is the Alpha Corvi system, where an allied warship has vanished. Alex can guess why.

Her fears prove true—Alpha Corvi is under new ownership. Alex must face the monsters from her childhood again as her regiment mounts a rescue operation to find and save the planet’s colonists. But this time, there is something terrifyingly different about their enemy. The Corps has evolved to meet the threat, but the Lankies have adapted as well—and they are more lethal than ever. What began as a rescue turns into a desperate fight for survival for Alex and her new friends, stranded on a hostile world forty-nine light-years from Earth. And the only way home goes right through the Lankies.

Plot errors, such as describing LtCol Grayson as Major Grayson when it's been years since the last Frontlines book, are very annoying. The narration is also not very good: they should have stuck with Luke Daniels. If you're not familiar with the Frontlines series I guess you could go with this series as stand-alone but it's got canon holes.

Plot errors abound

Characters are engaging, narrator is good despite my fears, story is familiar yet new enough. I am delighted so far with this new story line.

Worthy successor to the Front Lines series.

When Terms of Enlistment, book one of the Frontlines series, narrated by the most excellent Luke Daniels, was first available on Audible in 2014, I immediately became a fan.of author Marco Kloos and have subsequently followed each Audiobook as it came out, always waiting with considerable anticipation. And Corvus was no different.
It was well worth the wait, following Alex as she again faces the fearsome Lankies, this time on a planet not her own. My only complaint, but it is a big one, is the dreadful voice of the narrator Arrielle DeLisle. With another author I could have abandoned the book (as my husband commented on hearing her reading, "How can you listen to that?") But it wasn't another author, and Kloos'story with the ongoing personal development of both Alex and the survival struggle of humanity easily won out.

Highly recommended as a most enjoyable SF military story. It could stand alone, but why not first enjoy book.one of the Frontlines:Evolution series which tells of how Alex first became involved. Or, better yet, be transported to the arrival of the Lankies and the subsequent battles, with the original Frontlines series?
