But when her Denver family unexpectedly moves next door, the Avengers arrive searching for a mysterious energy signature, and Abby Lee Miller and Ava’s former *Dance Moms* family are mysteriously sent straight to her house, every secret Ava has kept comes crashing together. Now New York, Denver, Hawkins, and her childhood dance family are all under one roof—and Ava realizes someone deliberately brought every person she loves to Hawkins.
