Ben can’t believe it when his imaginary friend the Gorblimey becomes unimaginary. The Gorblimey is loyal and kind … and real! But Skeleton Keys is far from convinced by the Gorblimey’s friendly ways. He’s got the twitch, which is (almost) never wrong, and it’s telling him the Gorblimey is dangerous and needs banishing to the endless void of Oblivion. To send him packing, all he needs to do is open the door with his key-shaped bony finger … and order will be restored. But as Ben battles to save his new friend from Oblivion, the Gorblimey is soon the least of Skeleton Keys’ worries. For strange things happen when imaginations run wild and it seems that there’s more than one unimaginary in town. And the other unimaginary is definitely dangerous and out for revenge…
