Restore me by Tahereh Mafi

This book is the explosive fourth installment in the Shatter Me series, picking up just sixteen days after the events of Ignite Me . Juliette Ferrars is now the Supreme Commander of North America's Reestablishment, having killed her predecessor, Warner's father . She has Warner by her side, but instead of a victory lap, she finds herself drowning in the overwhelming responsibilities of leadership, political intrigue, and the watchful eyes of the world .

As Juliette struggles to project confidence while feeling completely out of her depth, Warner grapples with his own complex grief over the death of his tyrannical father, a secret he hides from her . The fragile peace is shattered when the children of the other global Supreme Commanders arrive for a tense "visit," and Juliette is shot by an unknown assassin .

Forced to confront a devastating truth about her past—including the existence of a sister she never knew—Juliette's trust in Warner is shattered . As political tensions reach a boiling point at a high-stakes symposium, a tragedy of catastrophic proportions forces Juliette to unleash her power in a way she never has before, leading to a shocking cliffhanger that uncovers a stunning connection to her real family and the life she had forgotten
