Het (Raph/OFC), 38,106 words
Summary: Idealogical differences threaten to divide the turtles when Raph drags his brothers in to help stop a kind of criminal they haven't faced before: a coldblooded serial killer.
Raph finds a surrogate family and an awesome girlfriend in a very poor area of the city. When they're threatened by a serial killer, Raph turns to his family for back up only to face their rejection and anger. A well-written, long fic (with 2 sequels!) with a great perspective on each of the turtles.
