Volume 4: The Heart's Desire is the fourth volume of Image Comics' The Walking Dead that includes issues 19-24. The group manages to quell Dexter's rebellion and further secure the prison. At the same time, a katana-wielding woman named Michonne arrives at the prison seeking refuge. Her arrival leads to a major schism within the group, and Rick's role as leader is questioned as the others start to fear for his sanity. The volume ends with one simple proclamation that will forever change the survivors of The Walking Dead.
