excerpt:
Nervously I held my grandfatherās hand and my flimsy sketch pad as we walked towards the bizarre mosaic covered house nicknamed, āThe eye of Gulgeeā. A regular visitor to Nathiagali, I had never been inside that strange house and with childish expectancy I visualised a fictional world, an exotic dreamland as fantastic as its exterior with the mysterious Gulgee at its centre, the wizard who held this world together through his powerful magic.
