Jeremy Austin and the Miervaldis was a mysterious and thrilling novel that kept me guessing what would happen next. The first thing that I liked was the whole concept and setting. I thought the book was really interesting that the characters were held hostage on a different planet in a different time period. Also, the characters and their backstories were intriguing to see what their lives were like before they were held captive on their planet. I liked reading about the planet and seeing the alien’s culture.  I think it was a bit too long which made it a little difficult to get through. I was also not engaged and interested in the story many times, but it started to pick up once I got farther in the book. Overall all this was a pretty good read so I would rate it 4 of 5 stars and recommend it to ages 13 and up that like science fiction and fantasy novels.
