The Millionaire's Dinner Party: An adaptation of the Cena Trimalchionis of Petronius

This is much better than Balme's Cupid and Psyche reader. The vocabulary is divided up by the chapter; so instead of going to the back of the book and searching through a mini dictionary, one would go to the back and search for Chapter 1 vocabulary. This allows you to memorize important vocabulary. Other than that it is just like Cupid and Psyche. But if you're an intermediate student like I am, it makes all the difference.
Read this THEN Cupid and Psyche (my teacher made us read the latter first). If not Cupid and Psyche, try to read at least one more lengthy adaptation.Then you will be ready for your first unadapted reader. Trust me you'll need all the practice you can get if you want to read unadapted Cicero.
