Swallowing Mercury by Wioletta Greg   {Reviewed by THOMAS}  Cleanly written and quickly read, this novella conjures a series of presumably autobiographical vignettes from Wiola’s childhood in a village in rural southern Poland in the 1980s, when tradition, superstition, Catholicism, poverty and Communism had roughly equal pulls upon village life. To say the book is without residue is not to say it is not memorable; the moments caught in Greg’s deceptively simple prismatic prose are clear and vivid and the development of her individual character from childhood into adolescence against the adult world and its limitations is subtly and convincingly portrayed.
