“Westland closure: Titles that are selling fast and a few personal recommendations,” by Chetana Divya Vasudev, Moneycontrol. (Because this happened too. In February, a year after DtS was released, Amazon decided to shutter Westland, which published the book. The announcement saw folks rushing to buy copies of Westland books before stocks run out.)
