Will there be a second of the Kane Cronicals?

There is no confirmed information about a second Kane Chronicles book. Rick Riordan, the author of the series, has not announced any plans for a sequel.

While fans have expressed interest in more adventures with Carter and Sadie, Riordan is currently focused on other projects, including the "Trials of Apollo" series and the "Magnus Chase" series.

It's always possible that a new Kane Chronicles book could be written in the future, but for now, there is no indication that it's in development.
