Ted and Kat watched their cousin Salim board the London Eye. But after half an hour it landed and everyone trooped off–except Salim. Where could he have gone? How on earth could he have disappeared into thin air? Ted and his older sister, Kat, become sleuthing partners, since the police are having no luck. Despite their prickly relationship, they overcome their differences to follow a trail of clues across London in a desperate bid to find their cousin. And ultimately it comes down to Ted, whose brain works in its own very unique way, to find the key to the mystery.
Torn apart by tragedies and the publicity they brought, siblings Smithy, Jack, and Madison, aged fourteen to sixteen, tap into their parent's courage to pull together and protect their brother Tris, nearly three, from further media exploitation and a much more sinister threat.
