Who are these Visitors from a planet few have ever heard of? They are charming, amusing and seemingly naïve but they are also weird, with strange taboos about being touched and never eating in public. Their way of speaking is also peculiar and they seem completely at sea with most technology. They claim to be descendants of Merculians marooned on Osterly centuries ago, however no away-team ever landed on Osterly.
Marlo becomes convinced they are hiding an alien life form in their midst who might be dangerous but his boss forbids him from digging further. Then Triani's young sibling Rio falls for one of them, but even he can't get any direct answers. Why can no one manage to contact their home planet Osterly? Is there something sinister hidden behind the smiles and childlike charm? What do they really want? And will they eventually bring disaster to their hosts?
