The London Eye Mystery by Siobhan Dowd

Quite a change from the historical fiction of my last novel! This story centres on Ted and Kat's missing cousin, Salim, who went up in the London Eye but didn't come down. The narrator, Ted, has a "syndrome" (on the autistic spectrum, perhaps?) which means his brain is "wired differently" from other people. He really likes the weather. This helps him to try and solve the problem. I read this book quickly. Very good.
