Cloak and Dagger : shades of grey
(Graphic Novel)

Tandy Bowen and Tyrone Johnson met as teenage runaways in New York City. Preyed upon by chemist Simon Marshal, Tandy and Tyrone were forced into an experimental drug trail that triggered laten mutant genes and gave them super-powers. Tandy developed the ability to generate and manipulate lightforce while Tyrone's body became a conduit for the darkforce dimension. The two banded together to use their powers to fight crime as...Cloak and Dagger.

"Tyrone Johnson and Tandy Bowen reunite as the inseparable duo Cloak and Dagger! They waged a citywide war on drugs, organized crime and corporate greed. Now, though, they have drifted apart--until a dangerous threat from their past resurfaces, forcing them to face their feelings! But there's a greater danger to their relationship than any villian: mistrust. And things don't get any better when Dagger begins investigating a series of murders, with victims who look like they've had the life sucked out of them. Ty must push his powers to the absolute limit to save hundreds of lives, while Tandy discovers the key to defeating their long-lost foe, the Grey! But it may come too late to save Cloak from being lost the darkness forever!"-- on back cover.
