Pinnacle, founded in New York City by David Zenter, specialised in original science fiction and action stories. Hardcover books were added to the list as Corwin Books in 1976. The company moved to Los Angeles in the same year. When science fiction editor Robert Silverberg left, the Futurian series collapsed. But the success of historical romance Love's Avenging Heart prompted a new line and successful line in historical romance. In 1980 Pinnacle returned to New York; it filed for bankruptcy in 1985 and eventually became part of First Tarent Corporation. Today it is part of Kensington Publishing Corp.
Kensington Publishing Corp. is the last remaining independent U.S. publisher of hardcover, trade and mass market paperback books. 2006 marks our 32nd year in business. From the time our very first book (Appointment in Dallas by Hugh McDonald), became a bestseller, Kensington has been known as an astute and determined David-vs.-Goliath publisher of titles in the full spectrum of categories, from fiction and romance to health and nonfiction. Kensington now accounts for about 7% of all mass market paperback sales in the U.S. Through the Kensington, Zebra, Pinnacle and Citadel press imprints, the company releases close to 600 new books per year and has a backlist of more than 3,000 titles.
