I can't remember much about it & I really want to figure it out. I've tried to look it up online, but haven't found it.

There is a man & woman who lost their child at a young age. I think it was a 2 yo boy. The boy drowned. The woman starts hearing the boys cry years later in the home. She thinks he is still around & something weird is going on. Her husband thinks she is crazy.... anybody have an idea what this book is? This is literally all I can remember without giving the end of the book away...
