A Book as a Line on the River was presented in the waters of the Delaware River in 2017 near Narrowsburg, NY. In that area the river separates New York state from Pennsylvania state.
The two states have different policies regarding fracking, a process to extract natural gas that needs access to large amounts of water. Many fracking sites were set in the upper Delaware watershed polluting a river whose waters are used for drinking in several cities in New York and New Jersey states.

The performance was planned as a way to repair a “tear” among the two states by metaphorically sewing the river.
