The Red Pyramid

For fans of Percy Jackson, this is Rick Riordan's other, not-as-good series based on the exact same concept. There's a noticeable drop in quality of characters and tightness of plot. I definitely still enjoyed it as a kid, though. The first book is definitely the best of the series, and is worth the read as a standalone if you ignore the foreboding dark clouds of doom that foreshadow the sequels.
