In the shadow-drenched halls of Collingwood Estate, Mary Jane Holmes explores the delicate intersection of tragedy and redemption. Darkness and Daylight introduces us to Edith Hastings, a girl of unknown lineage, and Richard Harrington, a man whose physical blindness is matched only by his internal grief. As Edith grows from a rescued waif into a woman of character, her world expands to include the volatile Nina and the watchful Arthur St. Claire. It is a story where secrets are the currency, and the ultimate climax hinges on a single question: can love ever truly outweigh the weight of a lifelong debt? - Summary by Celine Major
