Sisters of Isis Books in Order

Sisters of Isis brings Lynne Ewing's mythology-heavy YA style to Washington, D.C. At the center are three girls, Sudi, Meri, and Dalila, who begin as strangers and end up tied to the same ancient calling. A mysterious young priest named Abdel pulls them together, and what sounds impossible at first turns out to be true: they are descendants of pharaohs, with magical gifts that connect them to Isis and an old war that never really ended.

What makes the series fun is how different the girls are from one another. Sudi is social, impulsive, and used to moving through school life on charm. Meri is more restless and skeptical, with a strong independent streak. Dalila has been sheltered and trained in old Egyptian knowledge without fully understanding why. Once the magic wakes up, their differences do not disappear. If anything, they matter more, because each girl brings a different strength, weakness, and way of seeing danger.

The magic leans hard into Egyptian mythology.

The Sisters can cast spells from the Book of Thoth, transform into animal forms, and step into a world where ancient symbols and modern life constantly collide. The main threat comes from the cult of Anubis, which gives the books an ongoing enemy instead of a one-and-done problem. That means each novel has its own immediate conflict, but the larger story keeps building underneath.

Washington, D.C. gives the series a slightly different feel from Ewing's Los Angeles books. There are schools, parties, family pressures, and romance, but there is also a background of monuments, museums, political life, and old institutions that fits the Egyptian material surprisingly well. Meri's public family life, Dalila's connection to an Egyptologist uncle, and Sudi's everyday high school world help keep the series from feeling flat or repetitive.

Like Daughters of the Moon, these books rotate attention among the main girls. You are not just watching a team fight evil. You are seeing how each Sister reacts when magic starts messing with friendships, secrets, reputation, and the future she thought she understood. There are only four books, so the arc stays fairly tight. The tone is quick and readable, with enough mythology to feel sweeping but enough teen drama to keep it grounded.

If you want a series built on friendship, fate, and ancient magic without losing sight of lockers, crushes, and messy family dynamics, this is what to expect. The books move fast, the mythology is front and center, and the group bond is the heart of it. Start with The Summoning and let the world explain itself one revelation at a time.
