Kayla Knowles

Kayla is an Apollo demigod, a daughter of Apollo.

History
Kayla is among the Campers that go to New York City and fight for the Olympians. She and her half-brother Austin set traps along the Brooklyn Bridge with their half-brother Michael Yew directing them.

Kayla probably survived, and and was commanded by the new cabin counselor Will Solace, her half-brother, to look for Michael Yew. His body is never found, but he is most likely dead as this seems to be the general opinion at the memorial. However many people think he may have run adrift on Calypso's Island. His disappearance may be a plot device for a future book.
