[5] On October 5, 2015, during his book tour for The Sword of Summer, Rick Riordan announced a compilation of all the crossover stories titled Demigods and Magicians, released on April 5, 2016.

When they become trapped on the island by Setne (who is attempting to become a god using spells in the Book of Thoth), they try to contact Carter and Sadie Kane but fail.

Setne summons the goddess Wadjet in order to consume her essence and take the Crown of Lower Egypt from her, becoming master of essentially one-half the Egyptian world.

[6] Hypable highly praised the short story, writing "While previous installations, like "The Son of Sobek" and "The Staff of Serapis", have given us one small pairing at a time, "The Crown of Ptolemy" unites all four of our heroes, and it is brilliant.

It is nice to see such a myriad of heroes joining with little resistance, more than happy to work in conjunction in order to defeat the bad guy.

"[7] After the release of The Crown of Ptolemy, the Percy Jackson and Kane Chronicles crossover series was on the New York Times Best Seller list for the weeks of May 31 and June 7, 2015.
