Chronicles of the Avian Alliance (en Inglés) - J. J. Faun

When their parents vanish, Dove, Lark, Wren, and Jay discover they were never meant to live an ordinary life. They were meant to inherit something far bigger. Left alone in their family's estate, the siblings begin searching for answers. What they uncover instead is a hidden legacy their parents had been protecting them from-a connection to the Avian Alliance and a power that can bend time itself.

Four powerful factions, Emberward, Tide Callers, Sky Weavers, and Stoneforged have been waiting for signs of the Alliance's return. As the Rift begins to break through, it pushes into their world, spreading in ways that twist time, distort reality, and grow stronger with every passing moment. The Avalyn siblings are pulled deeper into a world they are prepared to face, one where every choice matters, and nothing stays the same for long.

If they want any chance of finding their parents and bringing their family back together, they will have to learn to trust each other, stand together, and face what's coming. If they don't, they may lose far more than the life they once knew.
