Just because a book costs nothing doesn't make it worth reading: Flash Gold, however, is one you can't afford to miss.
Though this novella most likely won't take more than a couple of days to read, it'll stick with you for longer. The steampunk technology is typical in many ways, but the Yukon setting--where such devices have not yet been fully accepted--adds a new twist. Interesting as the background is, though, it never overshadows the story itself, which races along nicely.
It's also worth mentioning that, although there are other books in the Flash Gold Chronicles, this one works perfectly well as a standalone story: great if you find yourself with just a little time to fill. However, I for one certainly intend to pick up the next in the series!
