This is a truly haunting, and at times creepy, collection. Many of these poems center on the ways women have been, and can be, invaded by the touch of others. She writes about hysterics, sexual abuse, and medicine (amongst other things). The title plays into this theme, invoking the glass armonica. A fragile, haunting, and beautiful instrument, it is played by touch - the friction between the hands and the glass produces the noise. I enjoyed the rawness of the voices Dunham brings to life, even as they unsettled me. An interesting, dark, and feminine read.
