“It was against my parents’ principles to talk about death,” Roz Chast writes in this graphic memoir. When she suggests planning for the inevitable, they react so negatively that she immediately drops the subject—as relieved as they are to have avoided a difficult conversation. With words, drawings and occasional photographs, Chast, a renowned New Yorker cartoonist, chronicles what happens as her parents’ health slowly fails and they try to muddle through, while she’s forced into a caregiving role. Her tale is sometimes heartbreaking, often funny and always brutally honest as she describes—and depicts—her own conflicted feelings. Her mother’s anger explodes from the page, as does her father’s bewilderment while dementia closes in on him. Better than words, her cartoons capture the raw, emotional truths of a dilemma that will be familiar to many readers. Chast’s memoir is harrowing but lit throughout by flashes of humor and her acute appreciation for the absurd.
