Fourteen year old twins Maeve and Myles Petrov live an ordinary life with foster parents in a small city in Russia. While the foster parents aren't abusive or horrid, they also don't love Maeve and Myles like parents should but they don't mind as they have each-other, a roof over their heads and food in their bellies. Meanwhile a few hours away live another set of twins, Lev and Luka Ivanov, also fourteen, with loving parents, brothers and grandparents Neither set of twins or any member of the family suspect that these twins were switched at birth and that Lev and Luka have Maeve and Myles's place until Lev got an injury where he needed a blood transfusion from his parents and a blood test showed no biological relation to the Ivanov's.

Estelle Hawthorne was never part of the game. She's seven years old. She likes ballet, vanilla cupcakes, and glitter (sorry, Grayson). Being the youngest-and the only girl-in a house full of Hawthorne boys means: someone is always carrying her someone is always panicking about her safety someone is always deeply regretting what they just said out loud This isn't a story about solving riddles or winning fortunes. It's a story about a tiny girl being loved loudly, protected fiercely, and accidentally causing absolute chaos simply by existing. Seven years old. Four brothers. Zero survival instincts. Welcome to Hawthorne House.
