—Boing Boing
“The Greatest Adventure is both a rousing adventure and a pioneering work of environmental fiction reflecting concerns over extractivism, the role of science in warfare, and the future of scientific inquiry.”
—Siobhan Maria Carroll, Associate Professor, University of Delaware
“A mixture of H. Rider Haggard, Conan Doyle, Roy Chapman Andrews, and a bottle of excellent gin.”
