Sienna has inherited a large fortune from an elderly aunt overseas and fulfils her lifelong dream of buying a manor house in the English countryside to live in. When she finds the perfect property, it needs a lot of renovating and structural work for which she hires architect Albert and interior designer Sammy. During the building works in the basement, some heavy equipment crashes into a wall. A stone becomes loose and falls down, revealing a hidden passageway beyond. The workers refuse to stay after sunset to explore because locals have been telling stories about a man-eating monster that comes out at night and devours everyone who comes too close to the ancient castle grounds. Because of this, Sienna must explore alone. When she finds a fortified wooden door and the key to open it, she doesn't expect her life to never be the same again. What she finds makes her blood run cold in her veins. But she can't go on screaming forever. And on second thought, she may have just unearthed the answer to the question of how to bring more energy into her life. Death is a good way to start, it seems. This short, sweet adult romance book is Book 4 of the series titled Tirza's Christmas Tales. As a standalone, it can be read independently of the other books in this series whose common threat is the seasonal theme of Christmas.
