I Am Cuba was his first traditionally published novel. His other historical novels are Love in a Time of Hate (August 2021), and At Every Hazard (August 2022). His love of history and mystery is combined in his 1920s Brooklyn 8 Ballo series starting with Velma Gone Awry (April 2023) and continuing with City Gone Askew (July 2024). Cost was a history major at Trinity College. He owned a mystery bookstore, a video store, and a gym, before serving a ten-year sentence as a junior high school teacher. In 2014, he was released and he began writing. And that's what he does: he writes histories and mysteries. Cost now lives in Brunswick, Maine, with his wife, Harper. There are four grown children: Brittany, Pearson, Miranda, and Ryan. A chocolate Lab and a basset hound round out the mix. He now spends his days at the computer, writing.
