What next?

I've finished singe variable calculus and I want a taste of pure mathematics before I go to university next September. I'm going to get a grasp of sets and proof first but what next? Number theory, analysis or what? Book recommendations would be ideal!

Agreed. Pure math is pointless unless you have time enough or money enough to study it. You could also go to some engineering school. In any case, biomedical engineering is perhaps worth pursuing. Contribute to health, and so that people can live longer to study pure math.
