Sue Miller, best-selling author of "While I Was Gone" and "The Senator's Wife," will discuss her latest book, "The Arsonist," with town resident and Publisher's Weekly contributing editor, Sybil Steinberg, on Wednesday at the Westport Library.

The program will take place at 7 p.m. in the library's McManus Room.

The novel is about a family and a community tested when an arsonist begins setting fire to homes of summer residents in a small New England town, according to publicity for the event.

"A provocative novel about the boundaries of relationships and the tenuous alliance between locals and summer residents when a crisis is at hand ... Miller, a pro at explicating family relationships as well as the fragile underpinnings of mature romance, brilliantly explores how her characters define what `home' means to them and the lengths they will go to protect it," Publishers Weekly described the novel.

Miller has written a number of best-selling novels, two of which have been made into feature films. Her book "While I Was Gone" was an Oprah Book Club pick in 2000. She is now a professor at Smith College, where she teaches creative writing classes.

Books will be available for purchase and signing at the program, which is free and open to the public.
