From the Literary Encyclopedia:
The abuses of power, the world of the military, the poverty of ideology, the pursuit of freedom, and the search for utopian aspirations, are, among others, some of the main themes running through his novels. Much of Mario Vargas Llosa's fiction could be described, at some level, as metafictional: while offering a “realist” plot with a verisimilar depiction of historical and human experience, his prose constantly questions the nature of reality, highlighting its illusive nature and foregrounding the brittle boundary between the “real” and the fictional. At the same time, however, behind the postmodern nature of some of his experimental prose, Llosa's work as a whole articulates an ethical and political vision at the centre of which lies resistance to, transgression of and rebellion against passive compliance to arbitrary social conventions.
