Lori Colley of Utube fame, who does Q vids is one of the essay writers in the amazon book. She admitted it in one of her vid and exposed the individual writers of WWG1WGA. So it's not a secret.
In short, the Q book is an anthology style book oor compilation of essays.
FWIW Lori is a female version of praying medic and I watch her Q vids.
