The Promise is an unforgettable novel of love and loss, by the Sunday Times bestseller Lucy Diamond.

‘Life isn’t a spreadsheet, Dan! You can’t fit people into boxes and charts.’

But Dan had never before come across a spreadsheet that had let him down. At the top of the page he’d listed all the best things about his brother that he wanted to emulate, then, in neat, typed columns below, he had thought up a number of ways in which he could try to fill in the gaps Patrick had left.

When faced with a sudden family tragedy, 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?
