'For Garney, 'Coming into his Twelfth' will not come fast enough to prevent him from getting school grades of 'G's (utterly useless) and 'H's (very utterly useless) or being bullied by Thatch Huddersby and his gang. But all this is thrust aside as he arrives at the 4 ¼ dimensional House of Two Rooms, the shared inheritance of all who have Pepper Barnicoat as their multi-grandfather, a mansion where everything is exactly nothing like it seems.
'Here Garney discovers that he is a descendant of one of the five Druidic families of Yore. Curiosity brings accident and Garney and his crippled cousin Eldeth adventure and misadventure their way to the walled city of Yore in the 4 ½ th dimension, where children wear earmuffs while playing stick-ball because – BLAM! – that extra half a dimension sure smarts.
'But here they are stuck. Neither can ever return to Two Rooms unless one finds a talent for hyperlogic, mathemagic, can dazzle a Mystal, and preferably, redeem the Barnicoat name, besmirched by Mad Barnicoat four Yonks ago. So Garney must set things right, as best a twelve-year-old with the weight of a whole civilisation on his shoulders can do.
'This is a wild, rambunctious book that
you will love.' (Publication summary)
