Blurb

The Red Pyramid is a 2010 fantasy adventure novel based on Egyptian mythology written by Rick Riordan. It is the first novel in The Kane Chronicles series.
The book is written as a recording by Carter and Sadie Kane. Carter and their father, Julius, go to London to visit Sadie. She had to beg her brother to live with her grandparents in London after their mother died. Julius takes them to the British Museum to study the Rosetta Stone. He actually has deeper motives and tries to summon Osiris, the Egyptian god of the Underworld, by using the stone as an anchor. It goes wrong when all the other four major gods are brought out and Set, the Egyptian god of Evil, imprisons Julius.
Carter and Sadie are taken to Brooklyn by their uncle, Amos. Amos decides to find Set after he imprisons Julius. In the library of the Brooklyn mansion, they begin to discover signs that both sides of their family are descended from the famous pharaohs. Julius's side of the family was descended from Narmer, while their dead mother, Ruby, had a family originated from Ramesses.
