Today I am pleased to present the first of the plenaries which were featured at The Shelley Conference 2017: Nora Crook's: Mary Shelley's Editing of Percy Bysshe Shelley. This lyrical, intimate and passionate presentation by one of the preeminent authorities on Percy and Mary Shelley provides insights into the extraordinary care with which Mary edited her husband's poetical works. I was spell bound. It is not to be missed. Grab a favourite beverage, pull up a chair and prepare to be beguiled!
