Children of the Storm is the 15th in a series of historical mystery novels, written by American writer Elizabeth Peters, first published in 2003.

Just after the Service d'Antiquités representative comes to inspect their work, several items disappear together with the conservator Cyrus had hired on Sethos's recommendation.

The Emersons meet up with Justin Fitzroyce, a young person with a strange mental malady, and his companion, François, who quickly develops a dislike of the family after Ramses mistakes his attentions to the boy for physical abuse.

Justin is travelling with his grandmother, the elderly, sometimes confused, Mrs Fitzroyce aboard an expensive dahabeah called Isis; also with them is her companion, who turns out to be Maryam, the teenage daughter of Sethos, fallen on hard times.

Along the way, the Emerson family is dogged by a series of mysterious events ranging from strange pranks to near-fatal accidents.

Most of these seem to be directed at the Arab servants, including Selim, who is badly injured when a motor-car imported by Emerson crashes as a result of the wheel-nuts having been removed.

The true motive is to steal the treasures found in the God's Wives tomb, which are all being taken by ship to the museum in Cairo, from Luxor.

The final chase scene has Amelia, Ramses, Sethos, Selim, Daoud, Cyrus, Walter, and Bertie sailing down-river; their aim is to board the Isis and free Emerson.
