Local writer Diane O’Brien (pictured) will give a talk on her new book, “Half of Every Couple: When Death Ends Marriage,” on Wednesday, February 13, at 7 p.m. at Lincolnville Community Library. The book is as much the story of a marriage — O’Brien and her husband, Wally, were married nearly 46 years — as it is a chronicle of her first year of widowhood. The 52 essays in the book are a year’s worth of O’Brien’s weekly column, This Week in Lincolnville, originally published on penbaypilot.com. O’Brien said that when writing them, she sometimes felt guilty pouring out her grief to readers who probably would prefer hearing about the goings-on in their town. Instead, people began urging her to keep writing about it. In addition to reading excerpts from the book during her program at the library, O’Brien will explore her thoughts behind the personal revelations in the essays, as well as the challenges of self-publishing. O’Brien has written a weekly Lincolnville town news column for nearly 40 years, first in The Camden Herald and then for penbaypilot.com. She is also the author of “Staying Put In Lincolnville, Maine” and “Ducktrap: Chronicles of a Maine Village.”
