The Hunger Games and my book

When I wrote The Fall two years ago I'd never actually heard of The Hunger Games.  I only discovered it about a year ago but never really felt the need to read it.  I'm glad I did read it; it's an excellent book, as is the sequel (I've yet to finish Mockingjay).  I did notice a few, but not many similarities, to The Fall, mainly a dystopian setting set after the end of the world.  I never realised how popular this genre was until I actually set out to publish my book.  Boy was I surprised!
