"Spirits in many different forms" are what you can find in legendary Iowa City writers' bar Dave's Foxhead Pub -- a.k.a. "The Foxhead" -- according to Lauren Haldeman, local poet and developer of the City of Literature web app.
Spirits also happen to be what Michelle Hoover is chasing after in her novel Bottomland, which was inspired by a mysterious family photograph she discovered in adulthood.
