Dear Philomel, is it too late to change this?

This book just came out on October 1st from Peachtree Press. It got a star from Publishers Weekly, and my friend Kendall (a judge for the Cybils this year) has given it a glowing review. As soon as Kendall gets back from her holiday trip, I get to read it.



Now this book (below) is slated to come out from Philomel on July 11, 2013. It sounds like a lot of fun (Ranma 1/2 meets physics) and I wish the author all good things, but...really, Philomel? You're giving a YA novel exactly the same title as another YA novel, a mere eight months after the first was released? 


Granted, Stephen Hawking has a book with the title The Theory of Everything, but it's non-fiction, and it has a subtitle: The Origin and Fate of the Universe. Lisa Grunwald also has a novel by that name, but it's adult, and it was published eleven years ago. Kari Luna's book is YA, and from the description, it seems like it will appeal to the same readers as J.J. Johnson's book. This is going to make word-of-mouth advertising pretty darn confusing. 
And so I'm wondering, Philomel: is it too late to change the title of Ms. Luna's book?
