Oddkins by Dean Koontz

This is disguised as a children’s tale about a magic toy maker's death and the quest of his magic toys to find the new toy maker who is across the town.  Their adversaries include some newly awakened toys made by the previous, evil, toy maker.  At the same time, the heir of the toy maker who thought his uncle was ridiculous and wants to sell the toy shop is pursued by a man who was just released from prison who wants to buy the shop to make more evil toys.  The turning point comes when the nephew sees the magic toys on their journey being pursued by the evil toys.
