Seventeen-year-old Henry has one adventure after another during his vacation!
With his friends, he gets a rusty handcar up and running. They explore a disused railway line and discover a mysterious tunnel. Girls have never played a role in Henry's life-until the pretty, disabled Karen appears on the scene... Will he manage to lure her out of her shell? During a short vacation with his grandparents in the small seaside resort of Reddingbourne, he happens to meet his "cousin by marriage," Lizzy. The initial dislike between two very different characters develops into a beautiful friendship-or is it something more? Before he knows it, Henry finds himself in a world of new, exhilarating feelings!
