Where Does The Lost Files Fit In The I Am Number Four Reading Order?

Lila Harper gave the Black quadruplets her virginity, her loyalty, her soul. Ethan, Marcus, Callum, and Davian were supposed to be her fated mates, destined to share her, protect her, love her. Instead, they rejected her on her eighteenth birthday, called her weak, and threw her out to die. Three years later, she's back and she's not the broken omega they discarded. Something happened the night they severed the bond, something that rewrote her from the inside out. Now she walks through Blackwood Territory with power that makes Alphas kneel and a hunger that won't stop until she's taken everything they love. The quadruplets want her back. The bond is screaming to reconnect. But Lila didn't survive the rejection to fall into their arms again. She survived to watch them beg. And when four Alphas who've never begged for anything start crawling back to the mate they destroyed? That's when the real violence begins.

Caitlin and Caleb awake in ancient Israel, in the year 33 A.D., and are amazed to find themselves in the time of Christ. <br><br>Ancient Israel is a place of holy sites, of ancient synagogues, of lost relics. It is the most spiritually charged place in the universe—and in 33 A.D., the year of Christ’s crucifixion, it is the most spiritually charged time. In the heart of its capitol, Jerusalem, lies the Holy Temple of Solomon, inside of which sits the Holy of Holies and the Ark of God. And in these streets, Christ will take his final steps to be crucified. <br><br>Jerusalem teems with people of all religious backgrounds and faiths, under the watchful eye of Roman soldiers, and their Prefect, Pontius Pilate. The city also has a dark side, with its labyrinthian streets and maze of alleyways leading to hidden secrets and Pagan temples. <br><br>Caitlin now, finally, has all four keys, but still, she must find her father. Her search takes her to Nazareth, to Capernaum, to Jerusalem, following a mystical trail of secrets and clues in the footsteps of Christ. It also takes her to the ancient Mount of Olives, to Aiden and his coven, and to more powerful secrets and relics than she’s ever known. At every turn, her father is just a step away. <br><br>But time is of the essence: Sam, turned to the dark side, has landed back in this time, too, and as he unites with Rexius, leader of the evil coven, they race to beat Caitlin to the Shield. Rexius will stop at nothing to destroy Caitlin and Caleb, and with Sam on his side, and a new army behind him, the odds are in his favor. <br><br>Making matters worse, Scarlet arrives back in time alone, separated from her parents. She roams the streets of Jerusalem on her own, with Ruth, and as she begins to discover her own powers, she also finds herself in graver danger than she’s ever been. Especially when she discovers that she is holding a great secret, too.

In a war-torn world where supernatural beings known as "subnaturals" or "subs" have emerged from hiding, triggering a global conflict that has claimed hundreds of thousands of lives, eighteen-year-old Lena Hargrove has spent the past six years as a ward of the state following her parents' deaths. Renowned as war heroes who sacrificed themselves to rescue their daughter from kidnappers, Lena's parents were largely absent throughout her childhood, leaving her with complicated feelings about their legacy and her own identity. As Lena struggles to understand her newfound identity and the abilities that begin to manifest, she uncovers a web of secrets about her parents' true role in the war. They weren't just fighting for humanity; they were part of a hidden movement working toward peace between humans and subnaturals. More importantly, Lena learns she was kidnapped not by chance. Hunted by extremists from both sides who either want to use her power or eliminate her entirely, Lena must navigate a dangerous landscape of political intrigue and ancient supernatural factions. Along the way, she assembles an unlikely group of allies—humans sympathetic to the sub cause, subs living in hiding among humans, and others like her caught between worlds. As her powers grow and her understanding of both sides deepens, Lena realizes that ending the war might require more than diplomacy or combat—it might demand a fundamental reimagining of what it means to be human or supernatural in a world where the boundaries between the two are increasingly blurred. But to fulfill her destiny, Lena must first confront the truth about her kidnapping, her parents' sacrifice, —a truth that will test her loyalty to both sides of her heritage and force her to decide what kind of world she wants to fight for.
