My Next Book

I'm still waiting on feedback about my most recent novel, the sequel to 'Madison', so I'm trying to keep myself busy in the meantime.  I really want my next book/series to be an epic trilogy, something that I would personally love to read, and I want it to be original.  I don't want to rehash stories that people have already told.  I'm looking to find my inspiration, and I just haven't found it yet.  I was thinking about trying my hand at Sci-Fi, but I don't want to write a book series too similar to the Ender's Game books.  I also don't want to rehash Hunger Games, or Twilight, or Fifty Shades of Grey, or The Lord of the Rings, or any other epic trilogy that has done extremely well.  I want to write something new, and intelligent, and enjoyable for anyone that might read it.
