Minor Memorial Library in Roxbury will present a book signing and author talk with historian Richard (Deej) Webb June 30 at 2 p.m.

Webb will discuss his just-published book “Boats Against the Current: The Honeymoon Summer of Scott and Zelda” at the South Street library.

Created as a companion piece to the upcoming release of the film “Gatsby in Connecticut: The Untold Story,” which features noted actors Sam Waterston and Keir Dullea, copies of the book will be available for purchase.

“The Great Gatsby” has long been synonymous with Long Island, but what if F. Scott Fitzgerald’s true inspiration came from Connecticut?

Certain elements of geography, location, and personality in Great Neck, long considered to be the setting for the novel, just don’t line up with the descriptions in the book.

However, they do fit in perfectly with another location, one that has been overlooked and even outright dismissed in the halls of academia: Westport.

Webb and his collaborator, director Robert Steven Williams, dug into the Princeton Archives, went through historical records; interviewed more than a dozen renowned Fitzgerald scholars; met with Scott and Zelda’s granddaughter, Bobbie Lanahan; and even tracked down a descendant of the original publisher, Charles Scribner III, answering unresolved questions about locations and personalities in the book and supporting Barbara Probst Solomon’s forgotten 1996 New Yorker article, which first laid out the argument for Westport being the model of East Egg.
