Parker and his family share a secret: they can, with the help of advanced technology, communicate between themselves through their thoughts.

When Parker, his dad, and sister Emma move to New York three years after his mother's death, Parker is having a hard time. He misses London and his friends, his father is distracted with his new job, and Emma is looking out for him instead of the other way around.

And then Parker's dad, on the cusp of a technological breakthrough, is kidnapped. Thanks to a message his dad sent telepathically before the signal cut off, Parker is suddenly on a rescue mission. Now Parker and Emma, along with their friend Michael and Polly the pig, must confront the only link to their father--a dangerous man locked away in an asylum. But all the signs point to one thing: the company his dad works for is up to something big. Huge. A perfectly sinister project that threatens far more than Parker's family. A project called SIX.
