The book is a classical coming-of-age story with mythological elements. It resembles the Percy Jackson series in the mixing of the modern world with Greek mythology. The book has a clear didactic message, in that the author dedicates this book “to all the horses everywhere; especially those who suffer under poor working conditions and horrific abuse”, and she asks the reader to help horses in need. This is an interesting means of linking past and present and for using a mythical creature as a symbol to help suffering animals today. Thus even before it begins, the book carries an important message. This idea will continue to echo throughout the book, especially with the emergence of Diana who will punish cruel horse-owners. Diana is described here as the guardian of animals and of nature.
The adolescent heroes of this story share similar feelings and insecurities, while each tries to find his/her place in the world. Furthermore, each of them discovers they have greater power than they initially thought and a special destiny, irrespective of whether they are Olympians or not. This is a common theme in many coming-of-age stories, when teenagers discover that their lives carry special meaning, that they can become heroes and rescue themselves (metaphorically) from a mundane existence. Emily actually going through death and rebirth, with her human part dying when she sacrifices herself as the fire of Olympus so that she becomes immortal (this we learn from the second book in the series, although it is not explained in this installment). Yet she continues to feel and act like a regular human. It is the ultimate sacrifice, and perhaps the ultimate fantasy of many teenagers, to become divinities. Yet it is achieved by her selfless sacrifice. It is not certain at this stage, whether Emily is a god now. All we know by the end of the book is that she died and was reborn. Like Hercules or even more, like Jesus, who sacrificed himself according to the gospels to save humanity. Emily sacrifices herself to save Olympus and consequently, Earth, as the two worlds are linked.
The role of adults as guiding figures is also shown in this book. While the adolescents need to take care of themselves alone and make their own decisions, they are ultimately assisted by Emily’s father and the goddess Diana. Thus there are good and bad adults who help to shape the young adults’ self-identities. Emily’s father and Diana are described as the good adults while the CRU members are the bad adults, who do not listen to Emily and her friends, do not believe in magic and try to harm and torture what they do not understand.
This book also deals with the sense of loss after the passing of loved ones. Emily deeply misses her mother and Joel is also an orphan who has lost his family and home, and suffers through the foster care system. This is a convenient plot mechanism which allows the children to escape their home and leave for Olympus without having any strings attached (Emily’s father helps them to hide and run away). The author’s personal experience of wide-ranging travels probably also influenced her decision to make the children so easily go from one place to another without becoming too attached to one place. The mythological connection, and especially Pegasus, is used as an essential healing tool for these children. Their connection to this mythical being (who, they strongly protest, is not merely a horse) helps them deal with their own feelings. Caring for the wounded Pegasus helps Emily and Joel put aside their own private suffering (about the loss of their family members) and care for someone else. They devote themselves to Pegasus who returns their affections. It gives them a new purpose to focus on and by helping him heal they are not preoccupied with their own pain but can gradually let go. They feel they have a purpose by helping this wounded wonderful creature. It accentuates the importance of animals as helping to ease trauma with children and also elderly people, something that research into animal-assisted therapy highlights.
Thanks to the combination of mythological components, that are the backbone of the story, with the modern elements, the book teaches that people are the same regardless of their origins, and they can unite and fight evil together. In contrast, the government officials are cruel people, who despise the unexplained and try to forcibly examine it, instead of lovingly accepting it. They are short-sighted and do not understand that their actions, which are allegedly meant to protect the world, will ultimately ruin it. The message is that fantasy and imagination, as well as living harmoniously with the nature around us, are crucial to the preservation of our world; magic, and belief, are of vital importance, and things should not be dismissed just because they sound implausible. The government agents judge everything by the standards of science and cold-calculations, although some of them are versed in mythology. Yet they dismiss this knowledge and forcibly try to understand the facts behind the Olympians: how they travel, what are their powers etc. They do not believe in magic or let themselves feel anything. With her initial remark on horses the author presents an ecological message in this story, about respecting animals, but she also emphasises the importance of stories, and naïve belief in them; of not seeing everything through scientific lenses. Children (and adults) need to use their imagination and to dream. Only then they can save the world.
