Wellington's trilogy is definitely highly imaginative. However, this last entry strays too far into fantasy for my liking as I am more of a zombie purist. Having said that, one must give the author credit for taking the genre outside of its comfort zone and spinning a very wild yarn. Be warned, some of it is head scratching and it does go on too long. To be frank - do not feel you have to finish the trilogy - I would have preferred stopping after Monster Nation.
