There have been two defining characteristics in Margaret Gibson's poetry over the past several years. She has eloquently explored bereavement and the enduring power of love as it pertains to her late husband David McKain's struggle with Alzheimer's disease, and she has fiercely explored the escalating global climate crisis.

With her latest collection, "The Glass Globe," Gibson, the Connecticut poet laureate, brings these passionate concerns together and thus completes a trilogy of books — preceded by the gorgeous, McKain-centric"Broken Cup" and "Not Hearing the Wood Thrush" — in profound and stunning fashion.

Gibson reads from "The Glass Globe" Tuesday in Westerly's Savoy Bookshop & Cafe. If you've never seen and heard Gibson deliver her own work, it's an experience not to be missed. The event is free, but registration is required.

Margaret Gibson, 6:30 p.m. Tuesday, Savoy Bookshop & Café,  10 Canal St., Westerly; free, registration required; www.banksquarebooks.com, (401) 213-3901.
