Lucie Brock-Broido's new collection is, in many ways, about the noncorporeal: Death, mourning, the tangled intangibles of language and the power of poetic imagination, like the "illusions" of the title, haunt this book. But Brock-Broido's work is simultaneously lush, tactile and physical — full of fabrics, flavors and colors, building up layers of objects and perceptions.
