The Bite on the Line by Simon Cantan is for free at most resellers (as far as I know).
I'm currently reading the fifth book in the Bytarend series (The Bite of Rust) and I suddenly realised that this series is turning into a real joy to read! So time to share it with you all
The first book, The Bite on the Line, isn't as mature yet as the one I'm currently reading, but it was enjoyable enough to get me hooked.
The series revolve around Bytarend, a mining town in the middle of nowhere. The feeling is a bit like the early Discworld books, seasoned with a slight touch of steampunk.
