Secrets of Rose Briar Hall by Kelsey James

1908, Long Island: For Millie Turner, the young and beautiful wife of a powerful New York stockbroker, Rose Briar Hall—a gleaming edifice of white marble on the North Shore—is more than a home. Every lavish detail speaks of Charles Turner’s status and wealth, and its stylish interior is testament to Millie’s sophistication. All that’s left is to prove her worthiness to be his bride. What better way than to throw a grand party for New York’s social elite?

After painstaking planning, the night of the event arrives and all is perfection—until Millie wakes to a cold, eerily quiet house, and a gray cloud where her memory should be. Can it be true that she has been in and out of consciousness for weeks, ever since the party took a terrifying turn? Millie recalls nothing. But her friends have shunned her, and it soon becomes clear that if she can’t find out what really happened that night, much more than her reputation will be at risk . . .

As the house that promised so much happiness begins to feel more like a prison, Millie wonders whether a woman alone, even a wealthy one, can ever be entirely safe. And if she succeeds in finding the truth, will it bring relief, or shake her marriage, and her life, to the core?
