New York Times bestselling author Lauren Willig returns with What Happens at Nightfall, a delightfully spooky contemporary romance about love, haunting, and a little bit of demon-hunting.

In the sprawling, beautifully 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 group of terrified boys and a strange, ancient key. Both lead to the 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, stricken by grief at the loss of their mother, are acting strangely. Why is his savvy tween daughter so taken with Jess, and why is his quiet son suddenly so popular—and so good at Latin? A haunting is afoot, and Jess seems to have more answers than she’s letting on. Despite the undeniable sparks flying between her and Adam, things are about to get very spooky indeed.

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 lays hidden in the Green-Wood’s splendid Vanderwilt marble mausoleum? 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.
