Thanks to NetGalley and Capstone for the opportunity to read and review The Boundless Sublime by Lili Wilkinson. Ruby and her mother are barely surviving after the loss of Anton, Ruby’s brother. Their grief is overwhelming and Ruby blames herself for what happened to Anton. She meets a unique young man and meets his “family”. His name is Fox and he lives in a sort of commune. Ruby goes with Fox to the Outreach building and she decides that she wants to learn more, so she attends the secret Institute and gets more than she bargained for. Any disobedience and you’re thrown in a cell-type room with no food or water for days until you are “elutriated” according to the leader who claims he’s the Daddy of all. Boundless Sublime frightens with its suspense and feelings of entrapment. As the synopsis states, this book is an “immersive thriller”, eye-opening as well as heartbreaking, with its tale of manipulation and a cult-like community led by a charlatan. 5 stars for a book I couldn’t put down!
