City of Lies by Lian Turner

This the second in the series that began with The Museum of Thieves. I like the first one, but it ended so completely, I wondered what Turner could do with the second one.  In order to make the second story work, Turner takes the children, Goldie, Toadspit and his little sister, Bonnie, out of Museum of Dunt and to a new city that has it's own quirky magic. In that city, there is a Festival of Lies where everyone has to speak and act contrary to their normal manner.There is also a magical "big lie"  floating around the city.  If a townsperson gets caught in a big lie, and asks the right question, and gives the right answer they can be temporarily transported into a state where the lie they said comes true. It is, again, and interesting premise and magic system and Turner comes up with, if not surprising, at least entertaining adventures for the children as they try to locate one another, and defeat the evil forces that have followed them to the new place.
