A book about three siblings with no mom and adventures.

[findmethisbook]

I once read a book 4-6 years ago. It was not new at the time, however I do not know how old it was, either. It wasn't too large, maybe a centimeter and a half thick. It wasn't all that hard either, you could just get through it easily. But I found myself liking the book. However, I have no idea what it was called nor who the author was.
Firstly, I can describe how the book's cover looked. It had the three siblings in the front. One in the middle and two on each side of him. Two boys and one girl. A boy in the middle, who I assume to be the eldest of the three, had blonde hair and a red scarf that covered his mouth. I do not know how the other two children looked(they were all ages 10-14 or something, I think). The background before them was mixes between light grey and dark grey. There were probably designs of trees in the back, but I really do not know.
The plot is something I can hardly grasp. I'll explain it the best I can, though. I know that the three siblings had lost their mother and I think lived with their single father. The eldest son lost his ability to speak at age 8, when their mother died. Also, I don't know if the mother died or disappeared. I think she died, though.Then, the brothers and sister went on adventures??? For a reason I cannot recall??? And then something about a middle-eastern prince or princess. Maybe they were middle-eastern. I don't remember, really.
Please, I would really appreciate it if someone were to help me with what this book is called! I would be extremely thankful. Thanks for reading this, if you did.

It's The Kneebone Boy, and I'll avoid further comment to save some spoilers.

If it's not The Kneebone Boy (and it'd be helpful to us as a community if you commented whether you think it is or is not), it could be Homecoming by Cynthia Voight. There are four siblings in this book: James, Sammy, Dicey, and a little sister whose name I can't remember... But their monther leaves them in the car in the parking lot of a mall and they have to survive without her.
