The London Eye Mystery by Siobhan Dowd

4.0

Imagine you and your sister have just started a one week school holiday.
Imagine your cousin Salim and his mom stop by London to visit for a couple of days before they move to New York City.
Imagine you and your sister and Salim are waiting in a long, long line at the London Eye for tickets.
A stranger comes up and offers a free ticket. You and Kat have been up in the London Eye before, and since Salim is your guest and has never been on the ride, you all agree he should take it.
You and your sister watch Salim board the car for the ride.
You and your sister watch the other members of his car get off half an hour later, but Salim does not disembark. And he's not in the car. Or in any of the other cars on the giant wheel. It's like he's disappeared off the face of the earth. His mother is hysterical. The police are baffled.
What do you do?
Well, if you are Ted, whose brain runs on its own unique operating system, or Ted's older sister Kat, whose motto has always been act first and come up with excuses later, you set about solving the mystery.
Is your brain wired close enough to Ted's that you'll be able to solve the mystery? The clues are there, but they're not easy to spot.
