Seven

Seven is the brother of Starr Carter in The Hate U Give. He is a baby during Concrete Rose, where Iesha leaves him with Maverick at three months old.

History
Seven Carter, Starr’s older half-brother, son of Maverick and Iesha. Seven is the oldest of the Carter children and fiercely protects all his siblings. He worries particularly for Kenya and Lyric, his half-sisters through Iesha, because of their dangerous home environment with King.

Seven lives between two households, with his dad (Maverick Carter), Lisa Carter, Starr Carter (his half sister) and Sekani Carter (his half brother). In the other household he lives with Iesha (mom), King (his step-father and Kenya and Lyrics dad), Kenya and lyric.

When he was a baby, it was thought that he was King's child until a DNA showed it was Mavericks. This is the exposition to Concrete Rose and what gives Maverick reason to his life.
