The Conditions of Will by Jessa Hastings

From the author of the Magnolia Parks universe and the Never series comes a fresh family drama with a heavy dose of romance and a twist of mystery.

"I can't remember the last time I couldn't get a handle on myself and my emotions, but the lid is slipping.

Something about the slipping lid feels like it's Sam Penny's fault. Like he broke the seal and he's slowly opening me up."

London-based Georgia Carter, professional lie detector and body-language savant, has long been estranged from her infuriating, close-minded, wealthy South Carolina family. After a falling-out years ago, the chasm runs deep between the black sheep—Georgia and her gay, alcoholic brother—and their parents and elder siblings. But when their father dies suddenly, Georgia returns to the States for the funeral…where she comes face-to-face with Sam Penny, her brother's AA sponsor.

Amid the tensions, dramas and revelations of the family reunion, Georgia and Sam are instantly drawn to each other. However, Georgia's brother also harbors feelings for Sam, and the last thing Georgia wants to do is hurt the only family she's ever really had.

When their father's will reveals a surprising bequest to a mysterious stranger, Georgia's ability to read people becomes crucial in unraveling her father's hidden past. The delicate balance within the family teeters, and secrets—both old and new—threaten to push them beyond the breaking point. 

There are only so many cracks a damaged family can take before it shatters.
