i just was in a small bookshop in limassol were they sell some english books and made a small check.
as i said, most books about cyprus in english, are historic.
there was one or two books, with cypriot fairy tailes or "cypriot traditional stories" in english , but not really a translation of gc authors.
nicosia has a couple of biggest bookshops perhaps you get something more there.
if you just started with greek, i believe that it would be difficult to read something in the gc dialect in the near future...
