Reviews

One of the most unsettling—and unforgettable—heroines I’ve ever met

Shari Lapena, New York Times bestselling author of The Couple Next Door

To Tell You the Truth is a spellbinding book about a missing child, and about the life of a writer. Bold, suspenseful, and impossible to put down. This one will stay with me for a long time

Samantha Downing, Sunday Times and USA Today bestselling author of My Lovely Wife

A dark, tense and very clever read with one of the best unreliable narrator’s I’ve ever come across. The plot is original and so compelling I couldn’t turn the pages fast enough to find out if Lucy Harper was telling the truth. This is an outstanding thriller and Gilly Macmillan is at the top of her game

Claire Douglas, Sunday Times bestselling author

Another fabulous read by Gilly Macmillan. When the main character is a thriller writer, you just know you’re in for the twistiest of rides!
