All the Colors of the Dark (2024) by British writer Chris Whitaker involves the abduction of children.

The year is 1975 and in the small town of Monta Clare, Missouri, girls are disappearing.

After 13-year-old Joseph ‘Patch’ McMacauley saves a girl who is being attacked by a man, he is abducted. Saint is an orphaned, tomboy girl who lives with her grandmother and is Patch's only close friend. Saint is determined to find Patch after he is abducted.

While he lies alone in a pitch-black room, Patch feels a hand in his and it is Grace who helps him survive.

When Patch finally escapes, Grace is nowhere to be found and Patch spends years searching for her.
