Yonah's diary


Date Entry
July 20
  • Devola and Popola came to keep me company today. They even sang a song for me! It was really great! I need to practice so I can sing to Dad when he gets back.
  • Devola and Popola went back home. That made me lonely, so I ran around singing songs as loud as I could. But then that got kinda weird and scary, so I stopped.
August 31
  • The village is buzzing with excitement and stuff today! I dunno what happened, but Devola told me not to worry. At first I thought it was a festival, but now I don't know.
  • I guess a Shade came near the village today. People kept coming up to me and saying "Boy, we sure wish your father was around!" And I said, "Me too! Dad could kick the Shade's butt!"
September 11
  • Today is Dad's birthday, but he's not here. So I just had a party by myself!
  • Dad said he would come back home for my birthday, but I want to celebrate his birthday once in a while!
September 21
  • I wish I could meet the Kainé lady Dad told me about. I bet she's really nice and always says nice things. I wonder if that's what my mom was like?
  • Today Devola said that Kainé is "put together in all the right places". I don't know what all of that means, but I wanna be like that when I grow up!
October 28
  • I was tired today, so I stayed home and hid in bed. I could still hear Devola's singing from somewhere, though. Listening to her always makes me happy.
  • These black marks keep showing up on my body. Sometimes I wonder if I'm going to turn into a goblin or something, but thinking about it makes my stomach hurt, so I try not to.
December 1
  • Today Popola sent me a new book about a great big tree. I really hope it has a happy ending. There's nothing worse than a sad tree.
  • In the book, the big tree kept on waiting and waiting. I have to wait a lot, too. I wish I could do something.
December 22
  • The snow won't stop falling, so Dad said he'd stay here with me until it stops. He'll probably leave again when it does, so I kinda hope it snows forever.
January 30
  • Dad came back! He came back to see me! Yaaay, Dad!
  • Dad left pretty quick. He said he just stopped by so he could see my face.
February 4
  • I'm gonna learn to make awesome food for Dad. I better start working on a new secret recipe.
  • Once I finish my secret dish, I'm gonna feed it to Dad! Then he'll see how helpful I can be.
March 16
  • The boy who's always running around outside gave me a super pretty flower today! I wonder if Popola knows what it's called?
  • The flower wasn't in any of Devola's books, so she said I could name it whatever I want. Maybe I'll name it after Dad!
April 5
  • Got a letter from Dad today! He's in a far-away town where he can see the ocean. I hope I can see the ocean someday. I bet it's huge!
  • Whenever I read a letter from Dad, I really feel like I need to see him again.
May 4
  • I write Dad letters every single day. He always worries about me, but I feel fine.
  • I wish Dad would send me letters every day like I do. But I know he's busy, so every other day is okay.

  • Devola and Popola came over to play with me. It was so much fun—they sang for me and everything! I'm gonna practice real hard and sing for Kainé!
July 23
  • I borrowed a book about the ocean from Popola. It says the water is salty and you can't drink it... but I bet you can drink a LITTLE and still be okay, right?
  • No letters today either. I wonder if Popola knows when more are going to get here? I'll have to ask her tomorrow!
July 26

  • Devola told me that I won't grow if I keep being picky about what I eat—but I still think carrots are gross.
