She just graduated from the Space Corps Academy.
Her first job: staying alive.
Elfrida Goto was expecting a holiday on Ganymede. Not a vermin hunt.

The colony is plagued by rogue genetically engineered critters, and the newly-minted Space Corps agents are expected to pitch in. Elfrida and her best friend take up the challenge, but the hunt turns into a nightmarish ordeal when they get lost in the subterranean caverns.

And, worst of all … they’re not alone.

In this explosive prequel to the Sol System Renegades series, Elfrida Goto’s first assignment takes her to the underbelly of the solar system, where nice girls finish last.

Felix R. Savage writes hard science fiction, space opera, and comedic science fiction. He has also occasionally been known to commit fantasy.

Felix has a long history associated with rebellion. He was born in the 1970s, a decade of American youth rebelling against the safe culture of their parents. He is married to a wonderful woman and they have two beautiful daughters. Together the four of them live in Tokyo serving their cat overlord and benevolent protector. Felix pounds the keyboard while not translating, delighting in his family, or catering to the whims of the family’s cat. He woke up one day to learn that he was a New York Times and USA Today bestselling author, but he continues to keep a low profile, and never stops watching out for any sign the lizard people have found him.

A bit silly and slight, buy never less than entertaining. The blurb compares it to Iain M Banks, but it felt more like Harry Harrison to me (which is no bad thing)

Not often do I read a book in one sitting, but today I positively devoured Crapkiller in three hours thirty minutes.

As a fan of the author’s Space Corps universe, I was expecting more of his brilliant narrative, and I was not disappointed in the least. Like the books Crapkiller is a prequel to, this one was a very enjoyable read. Once again I am privy to hard science fiction tempered by humor and excellent dialogue. Once again there is a darkness bordering on horror despite that humor. Once again powerful themes are explored and our insane possible future is sketched out for our consideration.

But this time Elfrida Goto’s hair is pink and she’s not quite the Girl Scout she evolves into in later installments. I confess that I found her wicked disregard for the rules refreshing; she is so crucified in later events that I kinda think she deserves to have that kind of fun more often. Something tells me, though, that the book after The Mercury Rebellion will probably not have too much of that. The solar system is become an ominous place indeed!

Editing was wonderfully done and, perhaps for the first time in the series, I was unable to find any typos whatsoever.

In all, I consider Crapkiller to be an excellent standalone novel (despite being a prequel) and a very appropriate beginning for what is quickly becoming my favorite sci-fi series.

Just finished reading “Crapkiller A Prequel to The Sol System Renegades Series”, by Felix R. Savage. This is my first read by this author, but will not be my last. This was a Sci-Fi/Horror/Tongue-in-Cheek type of a read. I found it very interesting, well written and very entertaining. The POCKs (Pieces of Crap with a K) not to be confused with POC (Persons of Color) are half Hamster half Human and in that respect reminded me of “Soylent Green”. This book stands alone in its concepts, and I look forward to reading the rest of this series.

Synopsis: She just graduated from the Space Corps Academy.
Her first job: staying alive.

I recieved this book as part of the SFWA scifi storybundle which I paid for.

I won't lie, I feel straight into the initial trap of this story, which is to say it looked like something very different from what it actually was. And I would say the author drew me into that net perfectly. To me this was an 80s cyberpunk romp with hellcats as the main characters and really I expected it was just going to be good clean multilating and military jargon.

What I really got was just as fun, but certainly a little smarter. We got to see how characters were viscerally changed by their experiences in a metaphorical rather than literal sense. It felt a lot like going into a job for the first time: there's the idea of how the world works and then there's experiencing the world for what it is. And a lot of things that appeared in this book were expanded on to satisfactory conclusions, world building happened and it felt natural, characters were wrong about things and right about other things and those things ended up turning a lot of quick decisions into lasting implications.

In short, I kind of want to read whatever is the sequel to this, and I didn't have to turn my brain off too much. I call that an accomplishment.

At first, I did not think I would enjoy this story. While I don't have a problem with flawed heroes, the character flaws in the main characters left me expecting a very different kind of story, one that I would not enjoy. I'm glad a pushed through a bit longer and found that the characters themselves were struggling with who/what they were.

For a short story introducting the characters and this universe, I think it did a pretty good job. The story held my interest and was even hard to put down by the end. I'll likely pick of the next book and see how the series pans out.

Loved it! First assignment- don't get into trouble on leave. Check. Second assignment - survive test. Sort of check. What is a UN space cadet to do when she stumbles upon an inter-space smuggling operation in the middle of her final test?! Take them down of course! Now on to bigger and better criminals!

Everyone's journey has to start somewhere.

For Elfrida Goto, recently graduated from the UN Space Corps, that journey begins on Ganymede.

This was a page-turner for me, the only reason I didn't finish it in one setting was that I had to get up the next morning!
This is a prequel to the Elfrida Goto trilogy, following Elfrida and her class last test before getting their assignment in the Space Corps. They're taken to Jupiter's moon Ganymede, and given a relatively straightforward, if somewhat bizarre, test. Or is it really so straightforward?

Prior to this, I've so far only read the first book in the series; The Galapagos Incident, but I was interested in knowing more about Elfrida's background before venturing further into the trilogy, and I feel that I have more "meat on the bone" now.
Sure, its rather short, but well worth a read if you are into this series, or perhaps as an introduction to it, I can see it working fine as that.

I rather enjoyed this, eventually - despite the unappealing title and at first sight a pair of equally unappealing lead characters. However they came through eventually, as did the also unattractive Kristiansen. The plot device(s) were well thought through and the final outcome and postings were well deserved. I very much liked the CMOT Sandwichmaker (Mr Dibbs - close enough but carefully avoiding plagiarism claims!)

I've already signed up for the next book - which is free, as was this copy,from the author's website.

Wonderful story! Some Space Academy graduates go to Ganymede for R&R. The R&R turns out to be post-grad testing. Their adventures take them wa-a-y past where the instructor expected! I'm hooked!

A worthy and very enjoyable prequel to the Solarian Saga.
One wonders if the United Nations Space Agency truly knew quite what they were doing when they recruited Elfrida Goto to their ranks. With her myriad piercings, cotton-candy pink hair and blasé attitude to rules, she does indeed seem an unlikely addition to their ranks. Contrary to all appearances, this nineteen year old rebel without a clue manages to rise to the occasion when her friends and colleagues need her most.
A delightfully offbeat story with quirky characters, wry humour, a suspenseful journey of discovery, all occurring amidst a vividly described backdrop of the icy expanse of Ganymede. It's definitely one that you shouldn't miss.
Highly recommended.

Be careful of what you eat? Elfrida just wants to get her dream job on Venus working for Space Corps saving people but the last test might be the one that she can't pass.
Their latest assignment is to cull the planet of POCKS which are actually huge hamsters but why the reasons given seem strange. Can she & her two friends find out the truth and get out alive.
Everything is not what it seems, there is smugglers that don't want anything to mess up their plans and even if it means that some young cadets go missing well things happen.
A really strange story and the truth about the hamsters was pretty gross.
I received a copy from the author.

"This is a test. A test. A test"
The new Space Corps graduates are sent to Ganemede prior to their allocations and, once there, have time for a little R & R before being allocated a final task: not one they had expected - they were asked to hunt hamsters, mutant ones, not dangerous but the size of a dog.
It all sounds a bit odd, but the POCKs are there, and docile - but, of course, there is more to it......
Snappily written and easy to read, this novella packs in loads of tension and surprises. It is fun and fast paced: a great little science fiction story

Good read

This was a little different but leave it to Felix to let you get so into a book and what's going on in the storyline that at the end he throws in a good little twist that you don't see coming. This was a good read and I think that the next book in the series will have more action now that the characters are known. I will let you know , sorry so late on posting but I had a lot to do over the holidays.

This was a great book ! I've been reading a lot of really heavy stuff lately, and decided a scifi thriller sounded like fun. This is a truly original science fiction story, in the classic sense, complete with giant space hamsters and UN space force cadets. Definitely a series I'm looking at reading the rest of.

Short but good

Just what you would expect from a training assignment. Star Corps stumbled upon something they weren't expected to. It was enough to impress the Dean and get them cushy assignments. A good little fast read.

This was quite a nice snack leading into the main series.

This was fun. The story is set in a colorful place with man interesting characters. Some places and parts of the plot remind me of some of the pulpy Asimov stories. I will be adding the others of the series to my reading list.

I thoroughly enjoyed Crapkillers. It kept me entertained and always guessing. They are darn funny parts too. I have recently become a fan of Felix R Savage's work. He has awesome story building talent and a wicked sense of humor.

I went into this assuming I'd be getting generic military sci fi, first mission crap. This is nothing like that. It's pretty good, with an interesting, yet somewhat believable look into the future (not sure about the UN running things, but other than that, everything seems believable).
