I add books to my Goodreads list as I go along. That's one way I keep track of my TBR list, although not every book I like and want to read is there. Took a look this morning at the To Read section and found 30 books.
Starting with the mysteries: There are a noir mystery, The Devil's Whisper by Miyuki Miyabe; Black Hole: A Novel of Psychological Suspense by Kitty Sewell; Murder For Hire: The Peruvian Pigeon by Dana Fredsti;
two cozies, To Hell in a Handbasket and A Real Basket Case by Beth Groundwater; a mystery series set in Shanghai, The Mao Case: An Inspector Chen Novel by Qiu Xialong;
plus an Alaskan series, Whisper to the Blood by Dana Stabenow, and a British mystery, Green for Danger by Christianna Brand. There's a mixture of authors - Japanese, Chinese, American, British. With mysteries set in different locations, I often learn about new places while enjoying a good plot.
The other genres I'll look at later. It's hard to tackle the list when other books keep cropping up, screaming at you to read them first.
