I hate this constant fight for survival. Should we just give them the genetic serum? Is it even worth it? "It's all going to be okay," Luke tells me for the thousandth time. "I'm pretty sure that the definition of 'okay' isn't thirteen-year-olds constantly running for their lives." I say. "Everything I had is gone." "What about me? I'm still here. Abbi, I'll never leave." He wraps his arms around me in a hug. I let my tears fall onto his shoulder. "Abbi?" I hear a voice behind me say. I turn around and look at Tris, not letting go of Luke. "It's time." Follow Caleb's daughter Abbi in her search for truth, as she discovers secrets that may change her life forever. She's determined to do whatever it takes to stand up for herself, her family, and her friends. And throughout the chaos, she meets Zeke's son Luke. Will she risk everything to save the people she loves?
