I know that this thread has been idle for a while but I have Ecce Romani I, II, and III, and III is great for an introduction to literature. A Distance Learning course that I’m enrolled in uses these (although I also bought them for myself, to look ahead and for days where I left my school textbook at school). III contains readings from Caesar, Eutropius, Livy, and Cicero as far as I know, and are pretty nice after Wheelock (which I used as self study). I’d recommend these to anyone, as it isn’t too hard, but isn’t easy. Fairly nice commentaries are included, and if you have no experience with Ecce Romani (I’m in year two now) you might look at books I and II (though they are fictional texts, like other textbooks such as Athenaze, also by Gilbert Lawell). It also includes grammar, comprehension questions, and a historical background on the texts.
