Frank and Nadia have been busy knocking down some of the pre-fab buildings they've had delivered and hiding the plans for the cross-island superhighway they were so keen on - because the fabulous Pari Thomson, creator of the magical botanical paradise Greenwild - is heading shorewards on her lily-pad for a visit. No surprise that this series of eco-thrillers has been a massive success, they're exciting enough to even distract Frank from his one-man campaign to make poets read aloud better. No surprise either that Nadia is finally ready for some time alone.

Ranger Hamza is in the house! Or would be if we had one. Frank and Nadia are all aflutter as Hamza comes in to land on the Island in the clutches of Assassin, the might Golden Eagle who lives round the corner from him in his Scottish home. Never takes the bins out but nobody dares mention it. With tales of pine marten poo, the superpower that is his dyslexia, and of course serious snack chat hamza offers something for everyone, and such is the enormity of his charm, intelligence and wit that two landlubbers who go by the names of Annabel and Lydia swim all the way out to the island to ask him some questions. Nadia and Frank might learn some proper interviewing techniques from them if they weren't too busy with their peurile Pogue pranks.

It's the one, it's the only... Charlie Higson!! Nadia's got a bit of a face on when she realises who's come to join her and Frank on the island, given that they've just created a book together, as this means breaking one of the island's golden rules - but soon she's ripping up said rule book (it's very thin) and eating it with glee as Charlie charms one and all with tales from his glorious career as a children's writer. If that's not enough, there are reflections on music and (semi?) quavers, and a race to the best James Bond dog pun, though all involved have to hang their heads in shame for missing Octopuppy.
