1. Probably The Iliad, written in 8th century BC, published in English in 1598
2. Depends on the series and if it‘s still interesting to me. JD Robb‘s In Death series is up to 56 and I still enjoy it. But other series, I‘ve burned out after 7 or 8.
3. Kate Daniels series by Ilona Andrews. I was sad but book 10 was a good place to end it.
