Object Lessons is a series of short, beautifully designed books about the hidden lives of ordinary things. We all wear hoods: the Grim Reaper, Red Riding Hood, torturers, executioners and the executed, athletes, laborers, anarchists, rappers, babies in onesies, and anyone who's ever grabbed a hoodie on a chilly day. Alison Kinney's Hood explores the material and symbolic vibrancy of this everyday garment and political semaphore, which often protects the powerful at the expense of the powerless-with deadly results. Kinney considers medieval clerics and the Klan, anti-hoodie campaigns and the Hooded Man of Abu Ghraib, the Inquisition and the murder of Trayvon Martin, uncovering both the hooded perpetrators of violence and the hooded victims in their sights. Object Lessons is published in partnership with an essay series in The Atlantic. Hood is searing. It describes the historical properties of the hood, but focuses on this object's modern-day connotations. Notably, it dissects the racial fear evoked by young black men in hoodies, as shown by the senseless killings of unarmed black males. It also touches on U.S. service members' use of hoods to mock and torture prisoners at Abu Ghraib. Verdict: Buy. Hoods can represent the (sometimes toxic) power of secret affiliations, from monks to Ku Klux Klan members. And clearly they can also be used by those in power to dehumanize others. In short, Hood does an excellent job of unspooling the many faces of hoods.
