SOLVED. Recent fantasy about magical sisters. [s]

[Sharon]

This book would have come out within the past five years, possibly the last two. I haven't actually read it, but I wanted to and now I can't find it. It is probably YA.

What I remember about the premise is that this is a world where magic is illegal, and the story centers around a family with five (I think) sisters who have magic powers that they have to hide. They hide them in plain sight by performing in a circus or carnival run by their father. I believe the idea of the story is that the older sisters are kidnapped or in trouble, and one of the younger ones has to save them.

Any ideas?

Sing Down the Stars maybe?

Yes, that's it! You did it! Months, librarians, message boards, finally! Thank you!
