Annihilation is one of the most atmospheric books I have ever had the pleasure of reading. This is a sci-fi suspense novel that loves to give detail to the environment but not the story, which involves a potentially unreliable narrator and many many mysteries of the land "Area X". It was hard for me to put down, but if you are not a fan of books ending with the mystery unsolved (or potentially even being closed to solved) then this may not be a book for you. Personally, I just want to go out and read the second and third books as soon as I can.
