Advice on Crime

Effers and anyone else reading this, I could use some help. I am doing some research on the depiction of interracial (romantic or sexual) relationships, interracial marriage, and/or mixed-race characters in modern U.S. crime fiction. If you know of any works that may be of interest, I would appreciate recommendations for novels, short stories, etc (NOT films). Also, I am looking for modern works, say in the past 2-3 decades (i.e. no Faulkner). Finally, I am looking at works that depict modern times (again - past 2-3 decades). Thus, stuff like Walter Mosely’s “Easy Rawlins”/Devil in a Blue Dress novels wouldn’t work. Thanks in advance.
