Herbie Brennan’s Forbidden Truths is a children’s non-fiction series that takes on some of the most popular mysteries and paranormal claims in accessible, entertaining fashion. Published between 2001 and 2007, the four books cover Atlantis, time travel, strange powers, and parallel worlds, each one mixing historical accounts, scientific speculation, and outright legends into a package aimed at curious young readers.
Brennan was well qualified to write these books, having spent decades researching and writing about the occult and unexplained for adult audiences. The Forbidden Truths series distills that knowledge for a younger readership without dumbing it down. Each book lays out the evidence for and against its central topic, trusting readers to form their own opinions rather than pushing a single conclusion.
The series works as both entertainment and a gentle introduction to critical thinking about extraordinary claims. Readers who go on to explore Brennan’s adult non-fiction will find the same topics covered in much greater depth, but the Forbidden Truths books remain a solid starting point for anyone between the ages of eight and twelve who has ever wondered whether Atlantis was real or whether time travel might be possible.
