Our relationship with the environmental activist Terry Tempest Williams dates back to her reading from Refuge, a lyrical essay about the deaths of her mother and grandmother, the radiation emitted from nuclear testing in Nevada, and shattered eggs in bird sanctuaries. Terry continues to practice her unique and beautiful skill of connecting disparate things, and with Finding Beauty In A Broken World (Pantheon, $26), she makes associations between her apprenticeship in a mosaic workshop in Ravenna, Italy;  the ecosystem of the grasslands and Colorado plateau, in which she discovers metaphorical and ecological mosaics, along with the threatened extinction of prairie dogs; and Rwanda, where she works with a Chinese-American artist to make a Tree of Life memorial mosaic on the one wall left standing in a village destroyed in 1993.  For Williams the mosaic images, fashioned from shards of shattered glass, resurrect beauty from brokenness.
