Desperate to escape his father's high expectations and his own grief in the aftermath of his mother's passing, sole heir Adrian Montague embarks on a search for his disowned siblings after discovering that he is not an only child. Sole heir to his father's estate, Adrian Montague is an up and coming political writer and engaged to an activist who challenges and inspires him. But most young Lords aren't battling the debilitating anxiety Adrian secretly lives with, or the growing fear that it might consume him and all he hopes to accomplish. In the wake of his mother's unexpected death, a keepsake of hers-- a piece of a broken spyglass-- Adrian finds himself face to face with an older brother he never knew he had. Henry "Monty" Montague has been living quietly in London for years, and his sudden appearance sends Adrian on a quest to unravel family secrets that only the spyglass can answer. Traveling to Europe to locate their sister Felicity, the Montague siblings are thrown into one final adventure as they face a ghostly legend that threatens their whole family. -- adapted from jacket
