The Eye of the World (Wheel of Time, #1)

Malcolm Tan The fiction series that got me hooked was The Wheel of Time series. Every time a new book was published in that LONG series, I immediately got hold of a copy from the bookstore and would spend the next few days reading the books since they were incredibly long. What appealed to me was the epic scale of the series, and how the various protagonists were very well characterised and captured my attention and imagination. (Source)

Mike Benkovich I'm cheating here (again) because this isn't a single book but a series. This is a 14 book fantasy epic written over DECADES! It took so long to complete and is so expansive the author died before he finished. The mantle was picked up by another author who finished the series in 2014. It's a story of massive scale featuring or launching any fantasy trope you can think of. If you think Game Of Thrones is good you will love this. (Source)
