Unite Me by Tahereh Mafi

Destroy Me tells the events between Shatter Me and Unravel Me from Warner’s point of view. Even though Juliette shot him in order to escape, Warner can’t stop thinking about her—and he’ll do anything to get her back. But when the Supreme Commander of The Reestablishment arrives, he has much different plans for Juliette. Plans Warner cannot allow.

Fracture Me is told from Adam’s perspective and bridges the gap between Unravel Me and Ignite Me. As the Omega Point rebels prepare to fight the Sector 45 soldiers, Adam’s more focused on the safety of Juliette, Kenji, and his brother.
