We've been studying ancients in school for a while, and last summer sometime I downloaded The Cat of Bubastes by GA Henty from Librivox.org. The children and I have been listening when we had 30 minute car trip here and there. For a time R-girl hated it, so we backed off, but finally convinced her to keep trying and she ended up enjoying it.
We all ended up enjoying the story of Amuba and Jethro, their treatment by Ameris' family during their enslavement in Egypt, their daring escape and return to the land of the Rebu with Ameris' children.
The reader either actively improved during his recording of the book, or we just got used to him. We'd all recommend the story despite its occasionally slow chapters.
