In order to work some Classical Greek into my diet, I recently picked up Thrasymachus: A New Greek Course from the Library. I’ve absolutely loved it so far. The meat of the book is a connected narrative in which a boy Thrasymachus encounters various stories and myths from the Greek world. It starts off very simple and progressively gets more difficult. There are some exercises and grammar in the book, but not much compared to the reading. I don’t think I would have wanted to use this as a first text, but as a reader for someone with some Greek knowledge it has been tremendous fun. Reading narrative is a nice change from the epistles I tend to read!

Yes, Thrasymachus is quite good. Not as extensive as Rouse’s Greek Boy, but it has some sparkling moments of humour hidden in there.
The bit about “how could she chop off his head if he didn’t have one” cracked me up pretty good ;-).
Alex,
Thanks for sharing this. I just read some in Ignatius (on the other side of reading Greek), but I must return to some classical reading. Perhaps I should pick up this story of Thrasymachus. ;-)
