Seaton is the author of 10 plays, the libretto for a solo opera, a spoken-word piece, and short fiction. Ruby Dee, Adilah Barnes, Kim Staunton, Michele Shay and Linda Gravatt appeared in a 1998 production of her first play, The Bridge Party, at the University of Michigan, a work inspired by local events. The play is anthologized in Strange Fruit: Plays on Lynching by American Women. Seaton's literary works have been featured by the Michigan State University in their Michigan Writers Series. Seaton wrote the libretto for the solo opera From the Diary of Sally Hemings for the composer William Bolcom. The fictional work is a depiction of the innermost thoughts of Sarah "Sally" Hemings, an enslaved woman of mixed race who is believed to have had a sexual relationship with Thomas Jefferson. Bolcom asked Seaton to create "diary" entries that would provide the text for his song cycle From The Diary of Sally Hemings. Seaton spent more than a year doing research to create a "diary" that would be historically plausible. As David Lewman pointed out in an article on Seaton's libretto, "It was a challenge. Though there is voluminous material on Jefferson and his period, there are no surviving examples of writing by Sally Hemings." The work was commissioned by mezzo-soprano Florence Quivar, who sang the piece at the Library of Congress's Coolidge Auditorium, the University Musical Society in Ann Arbor, Michigan, and the Herbst Theatre in San Francisco, and other similar venues. In 2010, soprano Alyson Cambridge performed From the Diary of Sally Hemings at Carnegie Hall. Seaton has continued to explore the relationship between Sally Hemings and the third president in two plays, Sally, a solo play, and A Bed Made in Heaven, a multi-character play. Sally premiered in 2003 at the New York State Writers Institute featuring . Seaton's play The Will, the story of an African-American family in Tennessee during Reconstruction, was performed in Idlewild, Michigan, the historic black resort, in 2008 as part of an event that focused on the connections between African-American culture and classical music. The character of Patti was inspired by the life of Elizabeth Taylor Greenfield, the African-American opera singer of the Civil War era. Seaton's comedy Martha Stewart Slept Here, set in an Indiana trailer park, premiered in 2008 and Estate Sale, a comedy set in a Cleveland suburb, in 2011. Music History, a play about African-American college students at the University of Illinois, SNCC, and the struggle for civil rights, was the focus of a 2010 symposium at Michigan State University on the ability of drama to illuminate issues of racial and social justice. Seaton is also the author of "Betty Price and George Nelson, Spreading the News about Modern Design", which appeared in Modernism magazine. Seaton taught creative writing and African-American literature at Central Michigan University for 15 years as a professor of English.
