Dark and Buried (House of Gray Book 4)

The Davenports have arrived. Every single one of them.
Amy Davenport survived her first year as Gray Haven's heir apparent by learning when to speak, when to smile, and when to get out of the way. She thought her second season would be easier.
She thought wrong.
Nicolas returns from a five-month silence with a fiancée on his arm. Days later, the patriarch of the Davenport family arrives with his ancient brother, his daughter-in-law, and an agenda no one will name aloud. Between masked balls, secret correspondence, and a household pulled taut with old grievances, Amy must hold her position against people who have spent centuries deciding how power works.
One of them has already told her to her face she does not belong here. The rest are more polite about it.
Can she prove them wrong before the season breaks open what they are all pretending to keep closed? Or has she stepped into a storm she cannot survive?
