Nick Bunker gets around. He was a financial journalist in London and then switched to investment banking, traveling widely throughout Asia, India, the U.S. and Russia. These days he’s a writer of big books that examine, in different ways, the past relationships between England and the U.S.

His first book was Making Haste from Babylon: The Mayflower Pilgrims and Their World. His most recent book, which he will discuss at the Katharine Cornell Theatre on Sunday, Oct. 5, is An Empire on the Edge, How Britain Came to Fight America. It looks at the Boston Tea Party and the origins of the American Revolution from the British side, trying to understand why the British leaders of the day had so little clue about their American counterparts and so little desire to understand the new world.

The event is co-hosted by the Bunch of Grapes Bookstore and the Martha’s Vineyard Museum.

Mr. Bunker will be joined on stage by Geraldine Brooks, another journalist turned best selling author. Ms. Brooks grew up in Australia and now lives in West Tisbury. She and Mr. Bunker will discuss his new book and hopefully a host of other subjects.

The event begins at 4 p.m. at 54 Spring street in Vineyard Haven. For more information, visit bunchofgrapes.com.
