Decodable mysteries set in Ancient Greece for striving readers aged 10-14.

Jason, Kass, Helen and Hector are off to participate in the Olympics! But when they get there, all is not as it seems. Can the demigods unravel the mystery before things take a dark turn?

Mount Olympus Mysteries is a new series of Hi-Lo chapter books tailored for striving readers aged 10-14. With gripping storylines and exciting line art, these action-packed tales will engage readers from start to end. Each book follows a group of teenage demigods who are disappointed that they, unlike other demigods, didn't inherit any powers. But by solving mysteries for the gods, they discover their skills, overcome self-doubt and prove themselves.

The series is written with a focus on morphology, which is critical for improving reading comprehension and spelling. This third book in the series focuses on common negative prefixes.

Serving as a vital bridge between decodable and mainstream books, the Mount Olympus Mysteries series will empower readers to confidently understand meaning from text alone, allowing them to become fluent independent readers.
