Anthem is short and very good — perfect place to start. 
Atlas Shrugged is her magnum opus — it’s awesome, but looong. 
We The Living is not about politics or economics (if you don’t like that), but it’s still heavily anti-communist (which is always a plus). 
Virtue of Selfishness is a good read if you want an introduction to Objectivism (non-fiction). 

 I agree here, Anthem was my first Rand book. 

 Anthem is perfect. It’s short too. Takes you an hour or two to read thru. Such a great novella.
