Fear of Frogs: Brimstone, Book 2 (Unabridged‪)‬

While Shax recovers from a near fatality, his shipmates have been busy. He's rather proud of them taking the initiative and finding them a lucrative cargo run. His pride turns to outright horror, though, when he finds out what sort of cargo. Unfortunately, he'll soon discover that a healthy fear of frogs doesn't prevent frog-driven disasters. Time travel has never been so messy.
