Kaitlyn Morgan never really knew where she belonged. Growing up in Erudite, she knew what she was destined for. A life of labwork and having unspeakable knowledge of everything. But when it is time to take the Test, a test that will determine what she's meant for, she finds out she doesn't fit in anywhere. So she chooses the one faction she always had her eyes on. Dauntless. The protectors of the city she called home. But little did she know that when she joined she would be put to the ultimate test and face Four, a guy with a deep past and the one who claims her as his.
