Sorry, I couldn't get past the first few pages. I do appreciate authors putting their work up here for free, but make sure it's something good, especially if you're hoping it'll entice us to buy some of your none-free ebooks.
Problems with the opening:
It starts with backstory, which we continue to get a lot of throughout.
We've got two characters talking to each other about things purely for the benefit of the reader.
Nothing happens for a while. Novels don't have to open in the middle of some life-or-death battle, but they should open with something interesting happening.
I suggest the author join Critters or another workshop to improve as a writer.
I came across this after buying Buroker's novel, The Emperor's Edge, from Amazon so this was a pleasant find. I was already familiar with the characters and loved this additional installment. I think it would work okay as an introduction to Buroker's work but this does take place after the events in the novel, which sets up the relationship between these two.
The dialogue between the characters is natural and fun. The ice breaking ship as a target for the bad guys is a neat and original device for a fantasy story. The plot moves along quickly, and the writing never gets in the way of the story. I disagree 100% with the fellow who said the prose was awkward. I wouldn't have known this was a self-published piece if I hadn't found it on Smashwords.
