Overall Content Rating: Parents Strongly Cautioned PG-13

This is a young-adult fantasy story centered on a teen navigating social life, family tension, and supernatural secrets tied to mages, vampires, and mixed heritage. Parents should expect recurring mild swearing when characters react to odd or frightening situations, plus occasional insults during disagreements. Violence stays relatively light compared with horror or war stories: much talk of blood relates to magic lineage or metaphor, while actual fighting shown in the samples is brief and often in a training or teasing context. There is no sexual content or LGBTQ+ theme in the flagged word samples, and the crude language is limited to name-calling rather than explicit vulgar jokes.

About this book

Enchantments will fail. Closet doors will open. And skeletons—all dressed in their finest secrets—will come out to dance. Raised in urban downtown New York, Gabrian holds no grand illusions of how life really works. And legends of magic and vampires, nothing more than a bunch of hocus pocus stuffed within book pages or painted on the big screen. But when a woman, no one else can see, enters her office and delivers a riddle filled warning about her intended fate, Gabrian's grip on sanity takes a big hit—terrified she is falling into madness. As Gabrian untangles secrets of her past, she discovers a powerful, hidden world of magic. A supernatural world in which there is no return. Now, she must choose a side. To walk in the light… or to run within the shadows of darkness. GREY, the first book in The Covenant of Shadows series of captivating urban fantasy novels, is new Vampire lore, a bit of romance and the supernatural, inspired by the beautiful minds that brought you City of Bones, Twilight and ACOTAR.
