<div class="bookreview">tings chak, <em>Undocumented: The Architecture of Migrant Detention</em> (Montreal: Architecture Observer, 2014), 112 pages, 22 euros ($30.60 from Amazon), paperback.</div> Over the past six years, more than 100,000 people, including children, have been jailed in Canada, many without charge, trial, or an end in sight, merely for being undocumented.… Locked away from the public eye, they become invisible.… Like the people within, immigrant detention centers are often invisible as well. Photos and drawings of these places are rarely public; access is even more limited. Canada has three designated immigrant prisons, and it also rents beds in government-run prisons to house over one-third of its detainees.… <em>Undocumented: The Architecture of Migrant Detention </em>begins to strip away at this invisibility. In graphic novel form, Toronto-based multidisciplinary artist tings chak draws the physical spaces of buildings in which immigrant detainees spend months, if not years. In crisp black and white lines, chak walks the reader through the journey of each of these 100,000+ people when they first enter an immigrant detention center.<p class="mrlink"><p class="mrpurchaselink"><a href="http://monthlyreview.org/index/volume-67-number-5" title="Vol. 67, No. 5: October 2015" target="_self">Click here to purchase a PDF version of this article at the <em>Monthly Review</em> website.</a></p>
