As a Chemical Engineer in training I loved this book. I read it twice and got the audio book.

Too expensive for a low end pulp science fiction novel. I’ve been plowing through the Horus Heresy for the last few weeks. At 16 per book, this habit is getting expensive quick. So I have decided to jump ship and just ordered a used paperback copy of Mechanicum elsewhere for 4. I will no longer be considering buying any digital Black Library releases at this unreasonable price, considering the length and quality of these novels, sorry.

meh. Kinda lame

A decent read, not the best in the Horus Hershey. Please fixes the typos: No quotations, but < or > signs on these pages: 161, 2 on 164, 170, 173, 184, 2 on 192, 200, 2 on 224, 268, 272, finally 3 on 273. Those need to be fixed, especially, after charging $16 it should have no errors.

It's a good book that gives an in depth look into the mechanicus as the Horus Heresy spreads to Mars. Unfortunately with that said its not worth what they are charging for the ebook. Back when it was $6-7 it was but not at $16. Find a used paperback copy and enjoy. 4 stars for the book but minus 3 for the price.

I agree with fallen

Good story, greedy company Why does the paperback cost less than an Ebook that doesn't need to be manufactured? I got the paperback for 8 bucks.
