Having read Sanderson's continuation of the epic Wheel of Time series and the breathtakingly original work he has produced on his own (so far i've only read The Way of Kings and the Mistborn trilogy) I had really high expectations of Elantris, despite being aware that it was his debut novel and could be a step back.
However, I was a little apprehensive because I like my fantasy complex and engaging and I just wasn't sure that a stand alone novel would be able to deliver.
Well Elantris didn't disappoint. The plot is rich and original with enough mystery to keep the reader intrigued despite giving the perspective of only three characters. In fact, I felt that the choice to focus on the main three characters was a master stroke; it meant that you got to know the characters intimitely without the necessity of extra books.
Now I don't believe in giving spoilers but I was slightly disappointed with the twist at the end of the book because I felt it was slightly incoherent. I think this reflects Sanderson's relative immaturity in drawing together a plot at the time.
Overall, Elantris is original, engaging and has the rarest of qualities... it is 'unputdownable' and I would thoroughly recommend it.
