Five on Brexit Island, Five Go Gluten Free, Five Give up the Booze, Five Go Parenting, Five Go on a Strategy Away Day (Enid Blyton for Grown Ups)

It is the night of the referendum and the Five have retired to Kirrin Island to enjoy the fresh air and sunshine, fed up with the rancour of public debate. George is firmly a 'remainer,' whilst Julian, who is in the 'Brexit' camp, is tolerated on the grounds that Anne cannot bear to go camping without him. (Timmy, largely apolitical but not keen on cats or rabbits, joins them too.)

The night is tempestuous in more ways than one. George has managed to rig up a satellite link with the mainland so they can keep abreast of the news, and they sit huddled around the fire, amidst some tension, as George's initial hope that the 'remainers' will triumph proves premature. Meanwhile, a violent storm whips up.

The damage is apparent as the new day dawns and George declares a new meaning for Brexit: Kirrin Island is exiting Britain. That is, until the red tape becomes too much of a challenge and their happy life together is under threat.

The Five have gone on their greatest adventure yet - to become an even better team! They are booked into an exciting hotel right next to the jolly motorway services, where the nice (if somewhat nervous and sweating and depressed) man teaches them a number of exercises that will make them work better.

But wait! Who's been sneaking messages through the hotel dumb waiter about secret assignations? Is there a smuggler's plot afoot? Or is Shelly from Production shagging Postroom Luke? All will be revealed . . .
