Preparing for Memoir Workshop

I just ordered three books by Mary Karr: The Liar's Club, Cherry, and Lit. Hope to read all three of these memoirs in preparation for a conversation I will attend in late October with the author, titled Inside the "Writer's Studio with Mary Karr." The description of the session sounds interesting. "Gossip could be leaked. Craft secrets uncovered. Deeper truths laid bare concerning: memory's fallibilities, the humidity of Texas, and if Radcliffe is actually a real live part of Harvard."
 
By attending programs such as this, I hope to hone my own writing skills. You may remember that memoir is one of the three categories of writing that I want to pursue.
