Keys to the Repository (2010) is a companion volume to Melissa de la Cruz’s Blue Bloods series, published between the fourth and fifth main novels. Rather than continuing the main storyline, it opens up the series’ world-building through a collection of supplementary material.
The book is framed as a set of files from the Repository of History, a Blue Blood archive located beneath the streets of New York City. It includes character dossiers, historical documents about the Blue Bloods’ origins, and short stories told from the perspectives of characters like Jack Force, Dylan Ward, and Kingsley Martin. For fans of the series, it fills in background details and offers glimpses into events mentioned but not fully shown in the main novels.
