I enjoy reading series/trilogies.
Some genres and tags of books that I fancy are:
Fantasy, Romantic, Action, stories based on historical events, mystery and thriller type books (Like Alex rider) and maybe even literature leaning towards eroticism/erotica (but not being the main component).

my personal faves, maybe you read them already: harry potter (a classic but i couldnt leave it out haha), the percy jackson series, mortal instruments, tigers quest serie (fantastic, indian mythology), trilogy called chosen ones, beautiful creatures, hush hush (4 books)... pretty much all fantastic with a romance in it and some adventure
