Well, the first chapter has already been released and there is a video where Rick Riordan reads the second chapter (at least parts of it). On a website it is said that Percy, Frank and Hazel go on a quest to free death and as we already know that, Thanatos, the personification of death will play a role in The Son of Neptune it is suspected that he has been captured and they have to free him.
