What next for Kris and Kate?

Can you solve Holly's puzzle? A vibrantly illustrated and enchanting book for 5 to 8 year olds. Kris and Kate continue their adventures - in and out of the sea, on an enchanted island, on the trees, in storms and in dead calms. And their adorable dog Holly is there too (helping or endangering?) - interested only in finding her bone again. But - would they all get home in time for tea? And where oh where is Holly's bone?
