To the Lighthouse by Cristy Burne
When opposites meet, the chances are that things will come unstuck somewhere along the way.
Emmy and Isaac meet on a holiday island. Emmy is a dare-devil and Isaac is cautious, due to an over-protective mum. Slowly but surely their escapades become more challenging, until inevitably an adventure proves a little too challenging!
This is a terrific little junior novel: well-written, with just the right balance of naughtiness and retribution. For ages 7 and up.
