Stephen King made a rare public appearance in New York City on Wednesday, walking along a busy sidewalk with the aid of a cane. The author, who turned 79 less than two months ago, wore a black sweater, a dark green puffer vest, jeans, sneakers and his familiar glasses.

King was in the city for an event celebrating “Other Worlds Than These,” released on October 6, according to his website. The novel is the final book in the fantasy trilogy he co-wrote with the late Peter Straub. The series began with “The Talisman” in 1984 and continued with “Black House” in 2001.

The event was scheduled for Wednesday evening at St. Ann’s Church in Brooklyn and hosted by independent bookstore Books Are Magic. King was set to speak with author Emma Straub, Peter Straub’s daughter. The event was announced on September 24 and sold out the same day, according to King’s website. General admission tickets cost $10, while signed-book bundles were priced at $41. A free livestream of the conversation is expected to be posted on YouTube later.

King is known for horror novels including “Carrie,” “The Shining,” “It” and “Misery,” many of which have been adapted for film, television or stage. His latest appearance coincided with the launch event for the concluding novel in his trilogy with Straub.
