There are many great stand-alones in fantasy, but, arguably, the genre is built on series. I guess, when you create an entire new world, just to place your story there, you’re tempted to re-use it 😉 And it pays better, and readers expect it. So, while Tolkien started with trilogy (that he is quoted to think about LotR as one book), his successors published longer and longer series or various length, renown and quality. For me, Belgariad and Dragonlance were gateways into post-tolkienian fantasy, and, after ca. 25 years of reading fantasy, there are still more huge – and reportedly great – series on my TBR.
Recently, I found myself on an extended business trip abroad, with only one book in my luggage (a 900-page one, but still 😉 ) and I visited an excellent second-hand bookshop that offered a pretty complete collection of one of the longest-going fantasy sagas, L.E. Modesitt’s Saga of Recluce. While not featured in most of the top tens, it’s often mentioned as an interesting series of novels, with carefully thought-through magic system and an innovative approach to the issue of chaos/order balance. I’ve always been interested by this last issue, as a huge fan of Zelazny‘s Amber. I bought the first four volumes, and now, after reading the first two, I reached a preliminary verdict.
And Tolkien it ain’t 😉
