All they needed to break the world was a door, and someone to open it.

Camford, 1920. Gilded and glittering, England's secret magical academy is no place for Clover, a commoner with neither connections nor magical blood. She's there only to find a cure for her brother Matthew, one of the few survivors of a deadly faerie attack on the battlefields of WWI.

When Clover catches the eye of golden boy Alden Lennox-Fontaine and his friends, doors that were previously closed to her are flung wide open, and she soon finds herself enmeshed in the seductive world of the country's magical aristocrats. But the summer she spends in Alden's orbit leaves a fateful mark: months of joyous friendship and mutual study come crashing down when experiments go awry, and old secrets are unearthed. The consequences will only be truly understood many years later, when it's too late...
