The Inevitable Undoing of Zahara Douglass

In April 1994, Zahara watched her twin sister, Annica, get hustled into a stranger's car and disappear-only to return to a world where no one remembers Annica ever existed. Not her mother. Not the police. No one.
Now, as the world braces for the looming Y2K crisis, Zahara finds evidence that proves her sister was real. Determined to uncover the truth, she hires a private investigator and begins digging into her family's shadowed past.

When the investigation leads to two charismatic men who once served with her father in Vietnam, Zahara realizes she and her sister may be pawns in a dangerous power struggle with unthinkable consequences.
To find her sister, Zahara must face the truth about her family, her memories, and the power lurking within her. But the sisters' reunion comes at a price-one that could unravel reality and bring about the end of the world.

'A moving story about sisterhood, lost souls and our complicated and potentially destructive relationship with technology. Leslye Penelope broke my heart in the best way possible. I can't remember the last time I loved a book this much or stayed up so late to finish it' Hollie Overton, author of Baby Doll
