Neptune War

Rate this book
Neptune's frozen outposts fall silent one by one. Strange signals from the edge of the Solar System draw the carrier ECS Vanguard into the darkness beyond the planets. There, humanity faces a new alien threat--the Blight. They have come to exterminate what they believe is their ancient enemy's latest puppet civilization.

Earth struggles to control the skies with fighters and throws its Lizard shock troops into bloody ground battles. While the war rages, Flex must uncover the truth about the hyperspace rivers connecting the stars, the mysterious Cure that terrorized Venus, and why the Blight believe humanity is already enslaved. The fate of two civilizations hangs in the balance—even as somewhere in the void, a greater horror stirs.

The Neptune War is the third explosive installment in the Pax Solis series, where first contact always turns into a fight to the finish.

Don't stop it's a great series

Each book is a good independent story but as each new book is added it gets better. There's so many possibilities, I can't wait to find out what happens next. . I'm hoping the next book gets released soon.

the best one yet

Loved it. Believable, hopeful, moral, ethical. Great naval and ground-pounder aspects. Fun interspecies relationships.

A great can’t-put-the-book-down read.

Thanks, David and B.V.!

A good Scfi story

I like that the story is a Scfi dream. Aliens, technology, and things that go boom.

Morally upright young man saving the world while cracking jokes with friends of all species, sexes, and non-biological.

Simple fun weekend reading.
