"Environmental advocate and nature writer Williams...celebrates the 'beauty of being brought together.' Tesserae, the cut stone and glass and enamel used in making mosaics, usher in her leitmotif: that it is elemental to human nature and a measure of our compassion to recompose a unity that has been shattered. 'I believe in the beauty of all things broken,' she writes, and mosaics provide a clear-cut example as she describes her apprenticeship in a mosaic workshop in Ravenna, Italy, where she found that 'a spiritual history of evolving pagan and Christian perspectives can be read in a dazzling narrative of cut stones and glass.'" —Kirkus Reviews
