The collection, published by Poetry Atlanta Press, is called On Occasion: Four Poets, One Year. The four - Karen, Head, Blake Leland, JC Reilly, and Robert E. Wood - regularly meet to share and critique one another's work. At one point, the four gave themselves a year-long writing assignment, and the collection features poems on the changes in seasons, holidays, vacations, and other life-altering events.
