Synopsis (from Amazon.com): In The Son of Neptune, Percy, Hazel, and Frank met in Camp Jupiter, the Roman equivalent of Camp Halfblood, and traveled to the land beyond the gods to complete a dangerous quest. The third book in the Heroes of Olympus series will unite them with Jason, Piper, and Leo. But they number only six–who will complete the Prophecy of Seven? The Greek and Roman demigods will have to cooperate in order to defeat the giants released by the Earth Mother, Gaea. Then they will have to sail together to the ancient land to find the Doors of Death. What exactly are the Doors of Death? Much of the prophecy remains a mystery. . . . With old friends and new friends joining forces, a marvelous ship, fearsome foes, and an exotic setting, The Mark of Athena promises to be another unforgettable adventure by master storyteller Rick Riordan.
Age: 9 or 10, but I would like to add that parents may want to read the books with their younger children and make it clear that the Greek and Roman gods aren’t real.
Inappropriate content: Annabeth and Percy sneak out of their rooms and fall together asleep in the stables. Nothing happens between them besides a few quick kisses.
My thoughts: I love Mark of Athena!!! It’s the best Heroes of Olympus book so far! Although, Rick Riordan took the term “cliffhanger” a little too literally when writing this book, in my opinion.
Sequels: The House of Hades and The Blood of Olympus.
