Plot Summary

Of Poseidon (2012) is a young adult paranormal romance by Anna Banks. The first book in The Syrena Legacy trilogy, it tells the story of a young girl who can talk to sea creatures and the prince of the sea who comes looking for her. This is a popular series, and in 2015, Of Poseidon was nominated for the Missouri Gateway Readers Award. The series is known for its unique take on the mermaid myth. Banks is the bestselling author of numerous young adult paranormal and contemporary books, although she is best known for The Syrena Legacy.

Of Poseidon is told from two points of view. Galen, the teenage son of Triton, is on a mission to keep an eye on humankind. His one connection to the human world is Dr. Milligan, an oceanographer. Galen once rescued Dr. Milligan, and the doctor helps Galen out when he can. He tells Galen that there is a new girl in town, who doesn’t look entirely human. Galen knows he must investigate, in case she’s one of his own people.

The girl, Emma McIntosh, is on holiday in Florida with her friend, Chloe. Finished surfing for the day, they get out of the water. Emma collides with Galen on the beach, accidentally hitting him with her surfboard. Galen is instantly attracted to her, but he can’t dwell on his feelings. He’s here to see if she can communicate with sea creatures and to take her back to the sea if that’s where she belongs.



While Emma is lost in conversation with Galen, Chloe goes into the sea again. She is attacked by a shark; Emma doesn’t notice until it’s too late. Emma warns the shark away from Chloe, but Chloe is already dead. Although Galen feels bad for Chloe, he’s more interested in Emma’s ability to talk to the shark. He realizes that she’s not only one of his people, but a member of Poseidon’s kingdom.

This is important because the kingdoms of Poseidon and Triton are at odds. Galen’s brother and heir to the throne, Grom, is supposed to marry a girl from Poseidon’s kingdom. This will ease rifts between their people, cementing an alliance. If Emma is from Poseidon, Galen must take her to his kingdom immediately so that she can be presented to Grom.

However, it is not going to be easy. First, Emma can’t change forms the way that Galen can, and she can’t go into the sea without dying eventually. Galen has to find out the extent of her abilities, so he can figure out a way to take her home. He explains to Emma what he thinks she is, and they work together to identify the limits of her strength.



Galen discovers that she can hold her breath much longer underwater than the average human, and she can communicate with the animals telepathically. Nevertheless, she can’t change into a mermaid, and so they must keep returning to land. Under pressure from his people to return home with answers, Galen can’t leave Emma.

Emma suggests they approach Dr. Milligan. Galen agrees this is a great idea. After some intense study, they ascertain that Emma is only half-mermaid, and so she’s not suitable for Gorm. Galen’s disappointed for his brother, but he’s more disappointed for himself. He has fallen for Emma, but it’s illegal for him to mate with a human.

At this point, Emma must return home from her vacation. Galen, however, arranges with Emma’s mother that she can stay out there for longer. Though it’s obvious that Galen is attracted to her, Emma gets upset when he intimidates other boys out of talking to her. She doesn’t see how she and Galen can be together, even if she finds herself falling in love with him, because they’re so different.



Emma knows there will come a time when she must say goodbye and return to her normal human life. Emma tries to prepare Galen for this, but he’s determined they’ll find a way to be together. However, they have yet to face their biggest obstacle—Galen must tell Emma about Gorm, and why he’s really been looking for her. However, he plans on avoiding this discussion for as long as possible.

Emma is worried that Galen is using her. She wonders if he would love her if she wasn’t one of his people. Galen, deep down, isn’t sure, and Emma senses this. She starts dating a boy called Mark, but Galen scares him off. Now, Emma’s sure that he loves her, and she trusts him.

Emma’s troubles aren’t over, though—they’re only beginning. Together, Galen and Emma work out that Emma’s mother is a long-lost Poseidon princess who chose to live in the human world. Emma is shattered by this; she feels she doesn’t belong anywhere. She has an identity crisis and goes in search of her birth mother, leaving Galen behind. The second book in the trilogy picks up from this point.
