Found begins when a mysterious plane full of babies appears at an airport gate, setting off a government cover-up that will haunt the children for thirteen years. Jonah Skidmore and his friend Chip Winston are among those babies, and their investigation into anonymous threatening letters leads them to an FBI agent named Reardon and a file listing them as survivors. A time traveler named JB guides the boys toward dangerous truths, while evidence on Chip's computer is erased by forces monitoring their every recorded move. The investigation leads to an adoption conference that turns out to be a trap, where the mastermind Hodge seals all the kidnapped children from history inside a cave. A final confrontation between rival time factions gives Jonah a device called the Elucidator, and he must choose between the past and the future for himself and the people he loves. Rather than accept either option, Jonah grabs onto Chip and his sister Katherine as they are hurled back to the 15th century.

After Jonah throws the Elucidator to JB, JB uses the device to send Hodge and Gary to time prison.

Before Jonah and Chip understand what the mysterious letters mean, the groundwork of the conspiracy is laid through a series of quieter but crucial discoveries. Government officials silenced witnesses at the airport, Chip received letters at two different addresses proving the notes were not a school prank, and Katherine captured the contents of Reardon's secret file on her phone camera instead of memorizing it. The investigation widened as Chip reached out to people on the witnesses list and tracked down a survivor named Daniella McCarthy, learning the FBI had advance knowledge of her family's move. A face-to-face meeting with Angela was arranged after an anonymous library invitation, and her sudden disappearance in the parking lot confirmed that time travel was real. By the time a conference flier arrived in the mail, Jonah had already pieced together that a safety note he left for his parents had exposed their research, and the listless basketball game with Katherine showed how much the stakes had grown.

The supporting moments that filled the gaps between each major turning point.

Jonah stands in the exact parking lot spot where Angela disappeared and takes the same step, but nothing happens.

Found is built on a sequence of revelations that force Jonah to abandon everything he thought was true about himself and the world. The story begins with a plane materializing out of thin air and ends with three children hurtling through centuries, but in between lie the smaller pivots that make each shock possible. Jonah's promise to help Chip kicks off the entire investigation, while details like a moved note in his drawer and a stranger with a flashlight in his bedroom confirm that unseen forces are watching. Angela's explanation of tachyons is the first moment the word time travel is spoken aloud, shifting the mystery from a government cover-up to something far stranger. The cave scene accelerates the danger, as Hodge's handprint scanner reveals he is testing the children's identities, and a group of kids naively frees Gary at the worst possible moment. In the end, Angela's account of how JB deliberately damaged time to maneuver the children into position reframes every seemingly coincidental event in the story.

The discoveries, decisions, and emotional shifts that redefined what Jonah thought he knew.
