Mr. Wicker's Window (Version 2) by DAWSON, Carley

When Christopher Mason walked into Mr. Wickers antique shop, he had no idea he would soon be embarking on a marvellous journey to China to find a wonderful tree made of jewels. He had no idea that Mr. Wicker was a magician and could travel through time. And that the tree was sought by others, not least among them the murderous Claggett Chew, a merchant in port and a pirate on the high seas, who also had knowledge of magic. But before Chris succeeded in quest, he would know of all these things and more. And of Mr. Wickers friends, the sailor Ned Cilley, Becky Boozer, and the African boy Amos, changed from wood to flesh. And Christopher Mason would never be same, after. (Introduction by Arthur Piantadosi)
