Gates’s characters, young or old or neither, are well educated, broadly knowledgeable, often creative and variously accomplished, whether as a doctor or a composer, an academic or a journalist. And every one of them carries a full supply of the human condition: parents in assisted-living – or assisted-dying – facilities, too many or too few people in their families and marriages, the ties that bind a sometimes messy knot, age an implacable foe, impulses pulling them away from comfort into distraction or catastrophe. Terrifyingly self-aware, they refuse to go gently – even when they’re going nowhere fast, in settings that range across the metropolitan and suburban Northeast to the countryside upstate and in New England.
