Our Goal

At Solve to Survive, our mission is to get kids off their screens and into stories that challenge their minds and spark their imagination. We believe in the power of real storytelling—where readers don’t just watch the adventure unfold, they live it. Each book is packed with heart-pounding action, clever puzzles, and clues that demand critical thinking. As kids turn the pages, they’re not just reading—they’re solving, decoding, and uncovering what happens next. Our goal is simple: to help kids fall in love with reading by giving them stories that make them feel smart, brave, and totally unstoppable.
