The Prometheus Project Books in Order

The Prometheus Project books are written for middle grade readers, but they are packed with the same big ideas and tight plotting as Douglas E Richards�27s adult work. The series follows siblings Ryan and Regan Resnick, whose scientist parents move them to what looks like the most boring town in America.0

The kids eventually discover that their parents are part of a top secret project exploring a vast alien city buried deep underground. In Trapped, Ryan and Regan break into the high security complex out of sheer curiosity, only to stumble into the alien city itself. A freak accident badly injures their mother and strands the adults, leaving the children to navigate bizarre alien environments, time travel, and the city�27s own defenses to have any hope of saving her.0

In Captured, the city itself falls into enemy hands when a team of elite soldiers led by a ruthless alien seizes control and takes the adult scientists hostage. Once again Ryan and Regan, as the only free members of the Prometheus team, have to outthink both human and alien foes to prevent an invasion of Earth that could start deep below their town.0

Stranded sends the Resnick kids through a portal to a primitive alien planet where predators, lava flows, and harsh terrain are constant threats. Surviving long enough to return home is the first challenge. The second is dealing with a new human adversary wielding an alien device powerful enough to become the most dangerous weapon on Earth.0

Throughout the trilogy, the books weave lessons about the scientific method, critical thinking, and real concepts from physics and biology into the story. Ryan and Regan rarely get handed answers; instead, they observe, hypothesize, and test their ideas, modeling for readers how curiosity and persistence can turn overwhelming problems into solvable ones.0

The result is a series that works both as page turning adventure and as an accessible introduction to science. While aimed at roughly ages nine to thirteen, many adults enjoy the mix of humor, danger, and genuine wonder at exploring an alien city that feels like a giant, deadly puzzle box.
