In Tent of Blue, Rachael Preston alternates between the dying days of English music hall and Vancouver in 1952 to tell the stories of Yvonne and her son Anton. Both are imprisoned, Yvonne by emotional ties to her abusive mother and, later, to a brutal impresario, and Anton by his disability and his mother's misery.

Tent of Blue is a story of captivity and escape, of discovering the strength to fight back against the world and seize freedom.
