The Promise is a unforgettable story about finding love, hope and joy in even the darkest moments, by the Sunday Times bestseller Lucy Diamond, author of The Secrets of Happiness.

'A bittersweet, big-hearted take on family dynamics, grief, and how to make happiness a priority' Woman and Home

When faced with the sudden death of his brother, Dan’s mission is clear. He puts together a project to help pick up the pieces and support his grieving sister-in-law Zoe, plus her young children. This is Dan’s promise - to ensure his family’s happiness, and to try and live up to the man his brother was.

But tying up loose ends brings a shocking secret to light, and calls into question everything Dan knew about his older brother. With more than just his promise on the line, Dan is faced with an ultimatum: Should he tell the truth and risk his family’s fragile happiness, or will his brother’s secrets end up becoming his own?

Real readers love The Promise: 'I cried and laughed' 'It was a beautifully written book from start to finish. Each night I couldn't wait to read the next chapter.' 'I literally cannot put it down.'
