It's a $120 workshop for only $30, so you can't beat the price.
But I'm a memoirist, so I'm not sure I need a course on character development...
Yes you do! Or at least, I, as a reader, think you do. My favorite memoirs are those where the characters are richly developed, a task that can sometimes get lost in our attempt to portray a communal, agreed-upon truth, when really a memoir is about the author's personal perception of what happened.
So memoirists, romance writers, thriller enthusiasts and all other scribes, come join me if you can.
