CC folks,
There are several good introduction to criminology books out there from a critical perspective.  I'd like to think the book Hugh Barlow and I just published makes that list.  More information here: http://www.rowmanlittlefield.com/Catalog/SingleBook.shtml?command=Search&db=^DB/CATALOG.db&eqSKUdata=0742561860&thepassedurl=[thepassedurl]
Thanks,
