By Ed Nawotka | Mar 12, 2021 Cavalier House Books, a new and used general trade bookstore in Denham Springs, La., opened in 2009, but its roots go back to 2005, when John Cavalier and his future wife Michelle Cavalier started supplying local elementary, middle, and high schools with required-reading titles while they were still students at Southeastern Louisiana University. At first, they filled their pickup truck with orders off of 18-wheelers on the highway because they were not allowed to deliver to residential homes, and they shipped books out of a 12-sq.-ft. shed in the backyard of John’s parent’s house in Denham Springs, a bedroom community across the river from Baton Rouge. “When things got busy, we would have palettes of books in the living room,” John said.
