It Ain’t All for Nothin’ [EPUB ebook] 

Life in Harlem isn’t easy, but Tippy and his grandmother are doing okay. Then Grandma Carrie gets sick, and Tippy goes to live with Lonnie, his father. Lonnie’s got his own thing going on, and he doesn’t have much room in his life for a son he barely knows — unless, that is, Tippy is willing to walk the far side of the fine line between right and wrong. Grandma Carrie always said if he had Jesus in his heart there wasn’t anything to worry about, but sometimes it’s not that simple. When the chips are down, will Tippy be able to call for help — and is there anyone out there who will listen?
