The Magicians (Lev Grossman)

Yes, The Magicians is a trilogy consisting of "The Magicians" (2009), "The Magician King" (2011), and "The Magician's Land" (2014). The trilogy follows Quentin Coldwater from his time at Brakebills University through his post-graduation adventures in Fillory and beyond.

Lev Grossman has acknowledged that the series draws on traditions from both C.S. Lewis's Chronicles of Narnia and J.K. Rowling's Harry Potter, but with a darker, more adult tone. Quentin Coldwater attends Brakebills University, a secret magical college, and the characters deal with depression, identity, and the realization that achieving their childhood fantasy world (Fillory) does not fix their personal problems.

The Syfy television adaptation, which ran from 2015 to 2020, diverges significantly from the books in plot details and character arcs while retaining the core premise and tone. For example, the TV series aged characters differently, changed who attends Brakebills together, and expanded the role of the Fillory and Further subplot, but fans of the books' dark humor and existential themes generally found the show faithful in spirit.

Fillory is a magical fantasy world that Quentin Coldwater discovers is real — it originates from a series of fictional children's books called "Fillory and Further" that Quentin read as a child, analogous to the Chronicles of Narnia. It serves as a central setting throughout the trilogy and its backstory is gradually revealed to be much darker than the children's books portrayed.
