Fourteen-year-old Kelly Braxton has always been different. Curious about the supernatural and fiercely devoted to her family, she is happiest fishing with friends and dreaming beyond the boundaries of her ordinary life in 1970s Britain.

Then tragedy strikes.

When Kelly loses both parents in devastating succession, everything familiar disappears. Grieving and uprooted, she and her siblings are eventually taken to America by an uncle they barely know. But a new country is only the beginning of Kelly’s transformation.

A mysterious visitor reveals an astonishing secret: Kelly and her twin brother, Ollie, are not entirely human. Their true origins lie far beyond Earth, in a world threatened by a ruthless enemy—and within each twin lies a power that has been waiting to awaken.

Drawn into a conflict bigger than anything she imagined, Kelly must confront danger, uncover the truth about her birth, and decide what kind of person she will become.

Part coming-of-age story, part otherworldly adventure, Kelly and the Power Within explores grief, identity, family, courage, and the extraordinary strength that can emerge from loss.
