YA/fantasy novel, translated from Japanese; possibly involving a haunted house

My boyfriend saw a book in Barnes and Noble a while ago that we haven't been able to find since. Here's what I know about it:

It was translated into English from Japanese, probably within the last couple of years.

I think it was a children's or YA novel, but not positive.

I believe it was about some kids who go through a haunted house and end up in a fantasy world.

The cover was very colorful.

I know it's super vague, but I'd be so grateful if you guys can help me figure it out!

Brave Story by Miyuki Miyabe? Only one boy, but you know. (I bought it a couple of years ago and it's been languishing in my TBR cupboard.) It was also made into a manga series. (ETA: and a movie and two video games)

And you are being terribly vague... What colors? Size? Paperback? Hardback?

I think that's it! Thanks!
