Ithaca is an Odyssey retelling, but told from the perspective of Odysseus' son, Telemachus. The first third of the book focuses on Telemachus' experiences on Ithaca up to the present day of the book. Odysseus has been gone for 16 years, and has been missing for eight, and other, strange men have started to live on Ithaca in hopes of becoming its new chief and marrying Penelope, Odysseus' wife. Telemachus eventually decides to take a journey to see Nestor on Pylos in order to find his father, and ends up travelling a little more extensively than he perhaps originally intended. In the next third of the book, we basically get the events of Odysseus' trip home from Troy as explained by Odysseus and a bard. The last third of the book follows Telmachus as he returns from his trip to find Odysseus, and then discovers that the man himself has come home.
The decision to retell the Odyssey from Telemachus' point of view was a great one, and it's those parts of the book that were, to me, the most successful. The book actually ends up being a great coming of age tale set against the backdrop of Greek mythology and culture. It made for an interesting read, and Telemachus' character and his relationship with his parents was flawed in a really genuine way. A+ for character development. However, the second third of the book, the sum up Odysseus' return journey bit, I could've done without. I read The Odyssey ages ago (in high school, like one does), but it's still enough of a pop culture reference (and yeah, I've read the Riordan books too, so that helps) that I knew the story already, and that part felt a little disjointed. I get why it was necessary, but ultimately, it harmed the narrative a bit. You are kind of pulled out of Telemachus' story to read the "best parts" version of Odysseus' journey, and it just felt rushed.
The Odysseus part aside, though, I really liked this book. I find myself liking it more and more the more I think about it. It's one of those books that stays with you for a while. If you are looking for a fantastical, gory, and ultimately very human coming of age tale, then this is for you. 4 stars.
