Underlay is a dark comic novel about horse racing and obsession and depression, not a science fiction story. It was first published in 1974, and much of the humor (and many of the comments) is(are) no longer socially acceptable, and there is something of a sexual content. I believe that it may be his longest novel, and he has been quoted as saying that it's his favorite of his books and believes that it is his best. The book is divided into forty-nine chapters, many of them with long titles that almost tell a story when read in sequence, and the prose and extended phrases are Malzberg at his desperate and depressed best. I enjoyed the read, though it's not my favorite of his works, and definitely not for everyone.
