'I loved The Promise' - Libby Page, author of The 24-Hour Café

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?
