SOLVED. YA/Children's Fantasy. Book with objects who act like charms, Queens who are the rulers, ghost and a Child girl. [s]

[Garfield]

I was really young when I read this book. Most of it was full of difficult words, and I only remember vaguely about it. It's about a little girl... I have no memory of the plot. I just remember about an objet who was a "magic chocolate charm", means that everything that the charm touch had a chocolate taste. I also remember about her being possibly link to the queen, like her hidden/lost child,or something. In this world, the queens rule without a king, btw. And the final hint, I can remember about some ghost characters, one in particularly, who was supposed to go with her in a house, but since he didn't visit it when he was still alive he couldn't get it. He could have done though while he was living, since he was invited in a party there, but he didn't feelt like it at the time.
I must add that I'm french, hense the broken english for this search ; but also the book may have been written by a french writer and never translate. So it's kinda a tricky request. But thanks to anyone who can possibly help me, though!

Garfield, is this book for kids or teens?

Around what year did you read this book? A range of years is fine.
