[Human]: I have heard the book Stargirl, is a good read. Could you advise who wrote that and when it was released ? [Assistant]: I love that book! It was written by Jerry Spinelli. He also wrote Loser. It was relased in 2000. [Human]: Loser looks like it is a Young-adult fiction, I will have to read that one! Do you have any other recommendations by Jerry Spinelli ? 
It is Young-Adult one of my favorite genres. I can't think of any others by Spinelli right now but Wicked Lovely is also young adult and is an excellent book. Have you read that one?
