If you've never been to Venice, Donna Leon's mystery series will make you want to go. If you've been to Venice, her books will make you feel like you are there again. She evokes the ambiance of Venice beautifully--it is almost another character.
They are easy reads so perfect before bed or in a sidewalk cafe in Dorsoduro, but well written, with an admirable hero and a host of interesting secondary characters. You'll experience the Italian view of Venice, not the tourist side.
Start with "Death at La Fenice." I bought it in a bookstore in London 25 years ago...and then spent the next decade looking for and requesting US bookstores carry her books. These days you can find them everywhere. A must read for Venice travelers and Venice lovers.
