Tedious reading. The book starts out good and has a satisfying ending however it's what's in between that's not pleasurable reading. The story reads more like a term paper for a chemistry class than like any kind of an adventure. Theories for solving the story's conflict are proposed, explored and dismissed in a way that can only be described as pure drudgery. What I found to be lacking was action, adventure, character development or plot twists to spice up this story. The author seemed more intent upon demonstrating his knowledge of science than enticing the reader. Not recommended as reading for anyone who appreciates the usual creativity associated with the genre of science fiction but perhaps those who like pure science texts would like this book.
