My Sister's Secret

From the bestselling author of I Died on a Tuesday comes an explosive new thriller about the ties—and lies—that bind us.

Two sisters bound by a secret that could tear them apart . . . Rosy is the responsible one, well-behaved and organized. Amy is the free spirit, always breaking the rules. But despite their differences, they can never be apart. Because only they know what happened that day and one wrong move could destroy them both.

When Amy confides in her new psychiatrist, he begins to suspect one sister is covering for the other. His gut tells him to run, but his own dark past draws him ever closer to the two women, and they to him.

As cracks form in the sisters' carefully constructed facade, one thing becomes clear: three's a crowd, and one of them has to go.
