New York Times bestselling author Lauren Willig returns with What Happens at Nightfall, a delightfully Gothic romantic adventure, complete with a little bit of demon-hunting.

In the sprawling Gothic expanse of Brooklyn’s Green-Wood Cemetery, some secrets refuse to stay buried.

Recently laid off and searching for purpose, Jess reluctantly joins her best friend on a supposedly fun nighttime cemetery tour. Separated from her group by accident, she discovers a bunch of terrified boys and a strange, ancient key. Both lead to Green-Wood’s surprisingly handsome resident arborist, Adam Chervinsky.

Recently widowed, Adam has more to protect than the leafy residents of Green-Wood. His children, still dealing with the loss of their mother, are acting strangely. A haunting is afoot, and Jess seems to know more than she’s letting on. Sparks fly between Jess and Adam–and the unquiet spirits of Green-Wood rise from their century-long slumber.

As Jess and Adam delve deeper into the cemetery’s haunted history, they uncover a Gilded Age curse, a ghostly socialite, and a demonic pact that stretches across generations. What lies hidden in the Green-Wood’s splendid Vanderwilt mausoleum? As the line between the living and the dead blurs, and the shadows of Green-Wood begin to stir with malevolent intent, Jess must confront not only the supernatural forces but a shocking connection to the past if she and Adam truly want to live happily ever after.
