We've met the monster. Now we learn the man. Mathias has many sides. Dangerous assassin being his most obvious, but beneath the killer is a great capacity for love. Can the beast be tamed? M squared has created a complicated tale of love lust and betrayal. Sinful is not just a runaway love affair or a renegade bloodfest. It's the creation of a family from Gemma and Mathias to Noah, Oskar, Rafe and all the other band of brothers. Love was the driving force for an epic ride.
