While listening to The Leviathan Chronicles the author, Christof Laputka, recommended another narrative fiction podcast series - the 7th Son trilogy by J.C. Hutchins. Since I enjoyed Leviathan so much, I figured I'd give it a shot.
The story begins with the assassination of the US president by a very unlikely person. As a result, seven very different men are gathered together by a secret government group to solve the deep conspiracy behind the shocking murder. Once together, one thing becomes very clear - each of them (despite minor differences) are the exact same person! They soon discover that the dangerous mastermind they hunt is the very man they were all cloned from...
Unlike Leviathan Chronicles, this series is more like a traditional audiobook, read and interpreted by the author alone. He manages to bring nuisance to each of the characters, and the story is action packed and full of enough twists and turns to keep you binge listening for days.
So, while you are waiting for the return of Orphan Black, you may want to take the time to get to know some new clones. You can find the free episodes on podiobooks.com (don't forget to tip your author!), and the Hutchin's website. The print version of the books are also available for purchase at B&N and Amazon.
