Nadia is back, in a new series. Spoilers ahead for the first.
It opens with Nadia helping Riordan and some other Shadow Hunters with a hunt for a man summoning Shadowlands monsters using a magical book.
Shortly thereafter, Tarlia has a little job for Nadia -- finding a murderer of a dragon. And Riordan has another job, finding out where the book from the hunt came from.
It involves a medical technology company that was shut down over a century ago, Russian bogatyrs in art, a singer who does not believe that Nadia does not listen to music, someone who apologizes before trying to kill, and more.
