Recommendations Please!

I am off to Budapest and Bratislava in November, and would love some recommendations for themed reading which I can divide between the time before I go and whilst I’m there.  Any recommendations of novels or children’s books set in the aforementioned cities (or the wider landscapes of Hungary and Slovakia), or those written by Hungarian and Slovakian authors would be marvellous.  I will also happily read non-fiction or historical accounts set in both countries.  Thank you very much in advance!
