Where There's Smoke - by Jodi Picoult.

I have started and finished this book in quick succession. It is a very short book [a novella?], hence I read it very quickly. Not really my favourite format or genre, but this author is a firm favourite and I enjoyed it. Here’s the blurb:

Even as a child, Serenity Jones knew she possessed unusual psychic gifts. Now, decades later, she's an acclaimed medium and host of her own widely viewed TV show, where she delivers messages to the living from loved ones who have died. Lately, though, her efforts to boost ratings and garner fame have compromised her clairvoyant instincts.

When Serenity books a young war widow to appear as a guest, the episode quickly unravels, stirring up a troubling controversy. And as she tries to undo the damage - to both her reputation and her show - Serenity finds that pride comes at a high price.
