I felt that this story had a lot of messages for younger readers

I adore the love between Lucas and Aidan. It shows how mean other kids can be, and how those words and actions can affect others.

Good for primary school kids.

Thank you Netgalley and the publisher for this e-Arc!
I am new to middle grade books and this book makes me want to read more. I always thought I was too old to enjoy middle grade (even though I am only 19 lol) but this book proved me wrong!

This is a story about Aidan who disappears for six days and then comes back with the story of a place called Aveninieu. No one believes him but his brother James (as much as he can at least). It is a story of brotherhood, family, life and growing up and dealing with the world.
I did really enjoy this book but it didn't WOW me. It was light and fun and had a interesting storyline. I wish it was longer and we got to "see" more of Aveninieu.
I would definitely suggest reading this if you like David's other books (which I love and if you haven't read them then you should!)

Also posted on Goodreads and soon to be on Instagram

This sweet MG story is about 11 yo Lucas and his 12 yo brother Aidan who disappears for six days and tells his family he has been in another world: Aveinieu. His parents don’t believe him; Lucas wants to, though. But isn’t Aidan’s story implausible? And does it matter if Aidan’s story is possible or not? Because Aidan is back safe and isn’t hurt, although Lucas notices he changed. Since his return, Aidan is quiet and seems lost. He only is happy when he tells stories about Aveinieu. But then Aidan’s story gets out, and everyone has an opinion.

I don’t read middle grade often, but I do read a lot of YA books. Never read one of David Levithan, though. I found <i>The mysterious disappearance of Aiden S</i> on NetGalley, and because I could read it without requesting it, I just gave it a go. And I’m glad I did.

I loved the relationship between the two brothers, how Lucas tried to get Aidan talking about Aveinieu and wanted to defend him when other kids at school got nasty. It shows kids what happens when they are mean to each other. Next to kids being jerks and brotherhood, I liked the way queer characters were presented in the story; aunt Brandi was the best!!

Sometimes I found the pacing a little slow, but overall I liked this story a lot!
