This is very much like pulp fiction, especially with the choice of cover. Makes me think of the 1950's pulp fiction covers where a there is an oil drawing of a pretty, alluring woman crawling along, the victim of something sinister. And reads like pulp fiction, too, with its emphasis on brutal, bleak warfare. It's not so much that there is a lot of fighting described--although there is still quite a bit--but characters in this book sure put up with a lot, such as betrayal of comrades whose minds have been taken over by aliens, by aliens that are so horrible that many probably would prefer suicide than to constantly fight them, and relentless military excursions (even the civilian population, such as families, has no rest from terror--thank goodness for some of Earth's past empire wars --if there had to be war at all--that focused on military targets and left families alone).
So is it good? Yes and no. It's certainly different, setting out a bleak, pretty much apocalyptic world. I applaud its simple message and its use of a female heroine. Yet, at times, it reads like a biography, rather than a story. Indeed, the book does start with Helga's past, then works its way up through her promotions through the ranks and her current fighting form. And, for me, the book is too bleak to enjoy. I like a bit of wonder and joy in my science fiction, with the winks conferred by the likes of Obi-wan Kenobi and Marty McFly. Poor Helga has no break at all... even her romantic relationships turn out to be traumatic, and there's always a chance her comrades can turn on her, corrupted by the aliens.
One thing I was wondering about... why are three-letter last names of characters capitalized, but any last names more than three letters not capitalized.
