For most of this book, I was saying it's an entirely run-of-the-mill SF; little to be bothered by, with the exception of what I'll say below about the main character, but next to nothing to remember, so much so that you could probably readily find hundreds like it and never recall which was which after reading them. Add to that the uncorrected conversion issues, resulting in many misspelled or simply wrong words, not to mention all the missing periods, and it's not hard to see why it's given away for free.
Still, if you somehow struggle through to the final portion, it does get notably better. Not enough to make up for the lack of, well, anything relevant up to that point, and definitely not enough to counterbalance the annoying macho hero that appears made of steel while hiding a troubled past and proving instantly irresistible to the hottest women
