I loved that Callie was very brave and is more concerned about Tanzy than she is about herself. She uses her knowledge of the wildlife and animals to help her move forward. She keeps Tanzy fed and safe, and understands how important it is for the cub to get back to her mother. Yes, she cuddles the lion, which seems like a bad idea to me personally, but given how cute the picture on the cover is, how could she not? It seems unlikely that this book would encourage young readers to go out to find lion cubs to cuddle, so it's good to see her caring for the the cub so diligently.
Line drawings of the Serengeti landscape and the flora and fauna there add an extra layer of immediacy to a fun animal story with a component of magical adventure.
