It took an in-depth look at a talk given at SCWBI's national conference on "The Art of the Deal, all about how a book is acquired. Presenters Brenda Bowen (agent with Sanford J Greenburger Associates, on the right) and Alessandra Balzer (VP & co-publisher of Balzer + Bray, an imprint of HarperCollins Children’s Books) used their roles as agent and editor to “act out” the process. (note: Brenda worked for Alessandra at Hyperion). They opened their talk with a short discussion of how an editor and agent like to work, that it’s both a business and personal relationship. Then they started their “case study” of the acquisition of a fictitious debut literary novel."
Even though it's a fictitious example, it's got details about royalty rates and how offers might change when more than one editor is involved that are fascinating.
