A castle keeps its secrets behind walls, which is exactly what flaps were invented for. This See Inside book opens a thirteenth century medieval castle the way no tour ever could: lift a flap and the banquet is underway, lift another and the tournament thunders past, lift again and a dramatic siege is scaling the walls you were just feasting behind.

The trick of the series is that the humor never comes at the price of the history. The scenes are genuinely accurate to medieval life, so a child giggling at the details of the great hall is also, quietly, learning how one actually worked. David Hancock's bright, detailed illustrations reward slow looking, and Katie Daynes keeps the text friendly and exact.

Sixteen sturdy board pages with embedded flaps, for curious readers aged six and up. Pairs naturally with Castle by David Macaulay, also at Stellar Luxe, when the question how was it built comes next.
