From a selfish perspective as an avid reader, it pains me to think about a "farewell tour" in the context of author Don Winslow. But it's true. The serially bestselling author, whose wildly diverse crime novels fuse literary elements with irresistible plotting and fascinating and polydimensional characters — as well as doses of witty dialogue and human connection amidst heart-crushing tragedy — is giving up his writing career.

His intelligent, fervent political beliefs were stoked to activism during the Trump administration and have further intensified to full-time commitment in the context of duty and personal conscience.

As such, Winslow's current book junket, on behalf of the wonderful novel "City On Fire" — the first in an already completed trilogy about a protracted war between Providence-based Irish and Italian mobs in the 1980s — brings him to Westerly's United Theatre Saturday. Sponsored by Savoy Bookshop & Vafe, Winslow will discuss "City of Fire" and sign books one last time.

Full disclosure: I'll be the onstage moderator at the event. And look in our Friday Daybreak section for an interview with Winslow.

Don Winlsow, 7 p.m. Saturday, United Theatre, 5 Canal St. Westerly; $10, $38 with signed copy; www.banksquarebooks.com, (401) 213-3901.
