I think this is a sale price, or in any case, it's very inexpensive for a book published by William Morrow, which is part of Harper Collins.
Aunty Lee's Delights by Ovidia Yu is a cozy mystery set in Singapore. I just finished it, and really enjoyed it. Although I usually like historical mysteries more than cozies, I also like books with a sense of locale. I've visited Singapore a few times, and this one rang true with its descriptions of Sentosa Island, the lushness of the vegetation, the oppressive heat and humidity, and the tourists (of which I was one).
It's listed at $1.99 at
Amazon US,
Kobo US, and
BN US, at least. This is a lot less than most William Morrow books, which is why I'm guessing it's a sale price.
I'm now looking forward to the next book,
Aunty Lee's Deadly Specials, which is coming at the end of September.
