May, 1914. Nestled in Sussex, the Summerhayes mansion seems the perfect country idyll. But with a long-running feud in the Summers family and tensions in Europe deepening, Summerhayes’ peaceful days are numbered.

For Elizabeth Summer, the lazy quiet of her home has become stifling. A chance meeting with Aiden Kellaway, an architect’s assistant, offers the secret promise of escape. But to secure her family’s future, Elizabeth must marry well. A man of trade falls far from her father’s uncompromising standards.

As the sweltering heat of 1914 builds to a storm, Elizabeth faces a choice between family loyalty and an uncertain future with the man she loves.

One thing is definite: this summer will change everything.
