Abigail Sorensen has spent her life trying to unwrap the events of 1990. It was the year she started receiving random chapters from a self-help book called The Guidebook in the post. It was also the year Robert, her brother, disappeared on the eve of her sixteenth birthday. She believes the absurdity of The Guidebook and the mystery of her brother's disappearance must be connected. Now thirty-five, owner of The Happiness Café and mother of four-year-old Oscar, Abigail has been invited to learn the truth behind The Guidebook at an all-expenses-paid retreat. What she finds will be unexpected, life-affirming, and heartbreaking. "Astonishingly wonderful and magical and moving and uplifting and DIFFERENT" MARIAN KEYES. "A brilliant, beautiful, hilarious, heart-breaking, extraordinary book. I say this without bias, only awe." LIANE MORIARTY
