Nothing in this novel is graphic, but I recommend Stronger Than You Know to mature readers only because it deals with various kinds of abuse.
Joy is finally removed from her mother and goes to live with her aunt and uncle and their children. However, Joy still needs to deal with her past. She has panic attacks and can't even be in the same room as her very kind uncle.
Slowly Joy begins to heal. Although this is a very upsetting book, the final message is people can heal from the past and most people are good and caring.
