The Heroes of Olympus, Book Four The House of Hades (Special Limited Edition)

In the fourth installment of the Heroes of Olympus series, "The House of Hades," Rick Riordan plunges young readers into a high-stakes adventure where demigods Hazel, Percy, Annabeth, and their friends face their greatest challenges yet. The crew of the Argo II is torn between returning home to prevent a war between demigod camps or venturing into the perilous underworld of Tartarus to rescue Percy and Annabeth and seal the Doors of Death. This action-packed chapter book, suitable for ages 9-12 (though the publisher lists 4-11, its length and complexity are better suited for older elementary readers), explores themes of bravery, loyalty, sacrifice, and the power of friendship against overwhelming odds. Parents should be aware of intense peril and scary scenes within Tartarus, but the overarching message is one of hope and perseverance.
