“The sinkhole opened up and swallowed Bobby Page’s mother whole.” That is the first line of Sinkhole, a horror novella by Grant Palmquist. After reading a first line like that, I am going to continue. Also, there is this sense of obligation when an author sends me a book that I had won in a contest. I promised I would write a review. With this novella, it is an easy promise to keep. My interest remained high until almost the end. I could have done without the last two or three pages but for readers who need to have a conclusion; they will be happy.
