why are there not more of these?

The combination of Craig and Lord Bray is again a winning one. If you like science fiction and have a sense of humour, you have to listen to this. Begin with Columbus Day though. these books are Epic.

Another great book in the series

I hope, and wish the series continues as I loved every book.
Big thanks to C Alanson and RC Bray for bringing it to life.

Well worth a read

Enjoyed this book, superb narration by R C Bray. This book needs to be listened to without distraction, there are a lot of characters and a lot of complex things going on and it’s easy to “lose the plot”
Maybe a little bit long? Could lose 3 or 4 hours I think easily and be as good.
Great Humour in the book that will have you lol at times.
Highly recommend!

Hurry up with Book 11. :P

I absolutely love this series. My second listen through each book. Craig Alanson is a fantastic, playful writer and R.C Bray brings every character to life perfectly. I can't wait for the next instalment.

More of the same......fine by me

After crushing the entire series in a few months at beginning of this year, I was left with a nail biting cliffhanger for 4 months after Valkyrie. With high anticipation I got through this in a week, slightly disappointing at the beginning, but soon back on track with Skippy the Magnificent. Pretty much more of the same & that works for me. RC Bray as ever outstanding & deserves a “juice box”

Perplexed

Yet another excellent story, full of Humour, wit and surprises. Skippy is da Beer Can. Great characters and new additions.. Brilliantly Read By The legend. RC Bray.

HOWEVER: I was left perplexed at the end, I wont write about it but I am puzzled as to the ending....... an Open ending if ever there was.

Wow!! Just... Wow

This is a fantastic book impeccably read by R C Bray!! It may actually be the best of the series. I laughed and cheered out loud as I listened to the story. There is tension and excitement as the story progresses and I genuinely didn’t want to stop listening until the end. Trust the Awesomeness and buy this book! Just make sure you have read the rest of the series first. You won’t regret it
