I read cozy and historical mysteries, a bit of Paranormal/UF, and to mix it up, I read science and gardening books on occasion.
The most common definition of exotic tends to be "tropical" - but I've lived almost my entire life in and on tropical beaches, which has rather leeched the "exotic" right out of them for me. If you'd asked me a decade ago, I might have argued for Australia as I'd always imagined it - in starry eyed wonder - as filled with kangaroos, koalas and blond haired surfers (don't judge - I really only had tourism ads to go by at the time) and after just about 8 years here, it's rather lost any exoticness.
But I'm enchanted by the setting of this mystery, and the one that preceded it: Murder on the Riviera (which I used for my Bastille Day entry). Sun, cliffs, the Riviera and grand-mere's house just sounds like heaven. The trust fund sounds pretty damned exotic to me too.
