This is a great ongoing series with First Second publishers and George O'Connor. My daughter (5th/6th grade at the time of reading, highly recommends the series). The books come complete with classroom guides, bibliographies, and research notes. From the publisher's website - "In OLYMPIANS, author & illustrator George O’Connor draws from primary documents to reconstruct and retell classic Greek myths. But these stories aren’t sedate, scholarly works. They’re action-packed, fast-paced, high-drama adventures, with monsters, romance, and not a few huge explosions. O’Connor’s vibrant, kinetic art brings ancient tales to undeniable life, in a perfect fusion of super-hero aesthetics and ancient Greek mythology".
