What a great book list, GeorgiaPeach, thanks for posting that. There were lots of old favorites, as well as some series to download before the next cruise.
I'd also suggest the Falco (Roman) mystery series by Lindsey Davis, as well as her more recent series which follows Falco's daughter, Flavia Albia.
Kerry *****, an Australian author, the Phryne Fisher mysteries, and the Corinna Chapman mysteries
Edited to add: For some reason CC is substituting asterisks for the name "*****". NO idea why.
Did it again, I guess just Google the Phryne Fisher mysteries for the author's name.
