Author Jeff Deischer has published a novella which is the prequel to his Heritage Universe series in which he reveals the origin of the Sentinels. This story is set in 1967 when the Charlton Action Heroes ended their publication runs and then began working together in the group known as the Sentinels. I remember those days and I am so pleased to see these characters back in action again!
