Another good read featuring fairies is [[The Thirteen Treasures by Michelle Harrison]]. It uses much of the same ingredients as the book reviewed above, the difference being it takes place in a contemporary setting. For older readers, I highly recommend giving Susanna Clarke's [[Jonathan Strange and Mr Norrell by Susanna Clarke|Jonathon Strange and Mr. Norrel]] a go. You may need some perseverance to get through 700 odd pages of stately paced plot, but the gorgeous Victorian language and stunning originality makes it well worth the effort.
