Just quote a couple of spoiler-free sentences the book you’re reading to tempt other readers.
Here is mine:-
“The French doors were swinging open and Rafe was asleep on the sofa, snoring, in a puddle of full ashtrays and empty glasses and scattered cushions and the smell of stale booze. The piano was speckled with shards of broken glass, curving and wicked on the glossy wood and yellowing keys, and there was a deep fresh goudge on the wall above it: someone had thrown something, a glass or an ashtray, and meant it.”
From “The Likeness” by Tana French.
