Crossover: Yellowstone × 9-1-1 After the devastating lawsuit against the 118, Eva "Buck" Buckley-the female version of Evan Buckley-has nothing left. The family she would have died for barely speaks to her anymore, and every shift reminds her she no longer belongs. When she returns to her loft one rainy evening, broken and exhausted, she finds the one person who has never failed to come back to her. Kayce Dutton. They met years ago while he was serving in the Army, becoming unlikely best friends through letters, phone calls, and the rare visits whenever he was stateside. One night of shared grief, whiskey, and honesty changes everything. By morning, they're in love. A week later, they're married. A month after that, Eva discovers she's carrying twins. Then tragedy strikes the Dutton family. Lee Dutton is dead. Without hesitation, Kayce takes his wife home to Montana, where Eva leaves the 118 behind forever. She expects to be treated as an outsider. Instead... Beth Dutton, feared by almost everyone, becomes fiercely protective of her, seeing a kindred spirit beneath Eva's brave smile. Rip Wheeler quietly claims her as the little sister he never had. The bunkhouse treats her like family. John Dutton welcomes her home. Only Jamie earns her distrust. As Eva's pregnancy progresses, the ranch slowly realizes she's expecting not one baby-but two boys. When Eva's estranged parents suddenly arrive at Yellowstone, everyone on the ranch witnesses firsthand the emotional neglect and cruelty that shaped the woman they now love. The Duttons make one thing very clear: She is one of them now. Months later, members of the 118 finally find her in Montana... Only to discover that the woman they pushed away has found the family she always deserved. "Just a heads up that I used AI tools to help brainstorm, expand my ideas, and edit some parts of this book.

When the Gods' Council gathers to judge humanity after seven million years of history, the verdict is unanimous: Humanity must be destroyed. Only one person stands against that decision-the eldest Valkyrie, Brunhilde. Refusing to let mankind vanish without a fight, she invokes the ancient tournament known as Ragnarök, where thirteen gods will battle thirteen champions of humanity. The rules are simple: First side to claim seven victories wins. If humanity loses, mankind will be erased forever. But as Brunhilde prepares her roster of Einherjar, she realizes that even history's greatest heroes may not be enough against the mightiest gods in existence. Then fate changes. A mysterious being known as Dark, the Lord Beyond Reality, appears before her. Existing beyond time, space, universes, and even the gods themselves, Dark presents Brunhilde with a powerful artifact-the Multiversal Selection Device. With it, she can summon champions not only from human history, but from countless anime universes across the multiverse. Heroes who have battled gods. Warriors who have defeated cosmic beings. Protectors who have saved worlds, dimensions, and entire realities. Soon, the arena of Ragnarök welcomes legendary fighters such as: Son Goku Vegeta Saitama Ichigo Kurosaki Naruto Uzumaki Monkey D. Luffy Sung Jinwoo Sora Seiya Ohma Zi-O Anos Voldigoad Rimuru Tempest Unlike the original Einherjar, many of these champions do not require a Volund to challenge the gods. They have already overcome divine beings, shattered impossible odds, and protected entire universes through their own strength. Now the gods face a terrifying possibility: For the first time in Ragnarök's history... Humanity might actually win. As gods, demons, heroes, kings, Riders, saints, and legends gather beneath the gaze of eternity, the greatest tournament ever conceived begins. Thirteen battles. Countless universes watching. One final question. Can the combined strength of the Anime Multive

At the same time, he continues to chase his dream of being a Hero and working to become the next Symbol of Peace. Disclaimer: I do not own either of these franchises.
