Constable Elke Veraart and her cyber-dog Meisje are peace keepers, patrolling the Babylon Eye. It's a good job, but there must be more to life than chasing smugglers and settling domestic disputes. Then three children ask Elke to find their mother, who's been missing for more than a year. The search attracts the wrong kind of attention. Elke and her young friends are in desperate danger. Unable to resist the powers that have been unleashed against her, Elke is swept out of the Babylon Eye and into another world.
While she struggles to regain her freedom, the children are unprotected. They must face, all alone, a new danger that stalks the corridors of the Babylon Eye."The Strange" is the third and final book in the Linked Worlds series.
