Feed your love of words at the Somerville News Writers Festival.

Now in its eighth year, this festival featuring local scribes and poets leads the way in helping our city's bookworms think globally, but read locally. On Saturday, a daytime Book Fair (11-4:30) kicks off the event, and readings (7 p.m.) by the likes of Steve Almond and Jennifer Haigh will fill the evening. For more info, please see our event listings here and here.
