A Stunning Debut

By Marisa Walz

From the bestselling author of Good Intentions comes a new psychological suspense--and a book within a book--that explores the thin line between fact and fiction for a novelist whose breakout debut is inspired by an explosive choice in her past.

Everyone thinks they know Delia's story. After all, her debut novel--inspired by a tragedy in her youth--has just launched her into overnight literary fame. Readers are obsessed. Critics call it "honest" and "unflinching." And for the first time in her life, Delia feels heard.

Then an anonymous message arrives: I was there. That's not what happened.

Delia knows better than to engage with an internet troll. Besides, her book isn't a memoir. It's fiction--inspired by her past, sure, but not a true retelling. But the implication that she hasn't told the truth hits a nerve she thought she healed long ago--because fourteen years earlier, in Byron Bluffs, Iowa, Delia was branded a liar after exposing the dark secrets that her best friend's family was hiding.

As more anonymous messages follow--each more insistent and unsettling than the last--Delia feels something she hasn't experienced in years: doubt. Suddenly, she's pulled back into the past she wrote to bury, and as the lines between truth, fiction, and memory blur, she must confront a terrifying possibility:

What if she didn't just change the story--what if she never knew the truth to begin with?

Told in alternating timelines, A Stunning Debut is a present-day mystery and haunting coming-of-age tale about truth, complicity, and the stories we tell ourselves to survive.
