Something is terribly wrong – Helios's chariot and the sun are missing! Can Helen, Kass, Jason and Hector solve the mystery and bring daytime back to Greece?

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 first book focuses on verb endings (s, es, ed, ing), adverb endings (ly) and comparatives and superlatives (er, est).

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.
