Flowers of Sulphur crackles with metaphorical energy. Over a decade in the making, this remarkable new book confirms Petrucci's reputation for exploring the gamut of human experience. It demonstrates, once again, his rare capacity to bridge the gap between science and poetry with power and authenticity. As with the best poets, thinking and feeling are, for Petrucci, a single act (George Szirtes). Indeed, just as we now know that light is both corpuscular and wave-like in nature, so Flowers of Sulphur is able to embody many, often seemingly paradoxical, qualities. These poems ring with complexity and clarity: like our quantum world, this award-winning collection reinvents itself moment to moment so as to unsettle, move and inspire us.
