What to read after The Picture of Dorian Gray?

Oxford Bookworms offer students at all levels the opportunity to extend their reading and appreciation of English. There are six stages, taking students from elementary to advanced level. At the lower stages, many of the texts have been specially written for the series, to provide elementary and lower-intermediate students with an introduction to real reading in English. At the higher stages, most of the books have been adapted from works originally published for native speakers.
