"Leviathan is funny and creative - Scott Westerfeld has imagined a world out of the depths of evolutionary history." Jawastew.livejournal.com, 13 Oct 09 "Fresh, exciting and eminently readable." My Favourite Books, 30 Sept 09 "A non-stop action story, with an incredibly imaginative steampunkish world-building, two very sympathetic protagonists and amazing illustrations and I loved every minute of it." The Book Smugglers, 30 Sept 09 "A really entertaining read, well-written and cleverly executed." About Books For Teens, 27 Oct 09 "A rollicking good yarn, packed to the gunnels with action, adventure and invention." Robert Grant in Sci-Fi London, 16 Sep 09 "All in all an awesome book which I enjoyed a lot. I will be eagerly awaiting Behemoth." The Overflowing Library, 11 Oct 2010
