Simon has been 13 for a long time. 2,000 years, in fact — ever since he died protecting his brothers during a Spartan attack on Athens. He’s spent his time since then in Hades, serving Persephone, learning from all the greatest thinkers who ever lived (and died), and trying every day to get out. When he finally makes his escape, he finds himself once again in the land of the living. Specifically, in a middle school boy’s bathroom. Simon is ready to live life to the fullest alongside his new friend Zeke, but Hades isn’t ready to let him go so easily. The Lord of the Underworld and his demons are set on getting him back, even if it means taking out Simon’s new mortal friends along the way.

Schmidt and Koertge mix the ancient and the modern in ways both hilarious and heartwarming. While Simon is confronted by the mysteries of smartphones and middle school, his new friends and classmates are surprised by his sincerity and gentleness. While reveling in his second chance at life, Simon brings a unique outlook and thankfulness that challenges the ways his new friends see and conduct themselves, Themes of loss and grief are present throughout the book, as are the contrasts between life and death.

Styx and Stones has just enough Greek mythology to hook those with a casual interest and fans of similar series such as Percy Jackson, although those with an especially deep interest may be disappointed by a lack of breadth and depth. Young readers with an interest in thrilling escapes and earnest adventures will enjoy reading about Simon and Zeke.
