My Brilliant Friend by Elena Ferrante (fiction 2012)

I'm late to the party. SO good, this story of a Neapolitan friendship.  Go get it.

Vita Brevis, a Gaius Ruso mystery by Ruth Downie (historical mystery, 2016)

I love this series - read it from the beginning.  Lovely details about the Eternal City, wonderful characters, new turns in Ruso's relationship with his Britannian wife Tilla.  Fun stuff.

Graveyard of the Hesperides, a Flavia Albia novel by Lindsey Davis (historical fiction 2016)

Another hit in the series.  I love this female detective in the City of Rome.  The characters are always varied and so well-researched, you feel like it's a real time and place.  I recommend starting at the beginning, and you'll be hooked.
