ALERT ONE SMALL SPOILER AHEAD. Wow. I know that Echo is billed as “YA” but this “OA” really loved this book. I do recommend the Audible version, the harmonica/other music is haunting, I can’t imagine the story without it. I can easily imagine a family listening to this book of four/five interwoven stories night after night. It’s set in tough times/situations -- pre-holocaust Germany, an orphanage, post-Pearl Harbor California -- and parents of younger kids should probably review first to make sure it’s appropriate -- but (sorry, here’s that small spoiler) importantly, no one IN the stories dies, although each story deals with hard times/losses. Still, it’s a hopeful, loving, life-goes-on, we-can-do-this kinda book, truly enjoyed it.
