Cloud Atlas meets Orphan Black in this epic dimension-bending trilogy by New York Times bestselling author Claudia Gray about a girl who must chase her father's killer through multiple dimensions.

Marguerite Caine's physicist parents are known for their groundbreaking achievements. Their most astonishing invention, called the Firebird, allows users to jump into multiple universes—and promises to revolutionize science forever. But then Marguerite's father is murdered, and the killer—her parent's handsome, enigmatic assistant Paul—escapes into another dimension before the law can touch him.

Marguerite refuses to let the man who destroyed her family go free. So she races after Paul through different universes, always leaping into another version of herself. But she also meets alternate versions of the people she knows—including Paul, whose life entangles with hers in increasingly familiar ways. Before long she begins to question Paul's guilt—as well as her own heart. And soon she discovers the truth behind her father's death is far more sinister than she expected.

A Thousand Pieces of You explores an amazingly intricate multi-universe where fate is unavoidable, the truth elusive, and love the greatest mystery of all.

• A High-Stakes Chase: Marguerite will stop at nothing to hunt down Paul, the man she thinks murdered her father. But this thrilling pursuit across parallel universes will test everything she believes about him—and herself.
• A Mind-Bending Love Triangle: In every new reality, she finds herself drawn to the enigmatic Paul. But her loyal best friend Theo is also on the hunt, forcing her to question where her heart truly belongs.
• Stunning Alternate Worlds: From a futuristic London to a Russia still ruled by tsars, Marguerite must navigate breathtakingly different timelines where one different choice changed the course of history.
• A Reality-Shattering Conspiracy: The truth of her father's death is bigger than a single murder. It’s a plot that spans the multiverse and could change the fate of every world.
