The Arcadia Project Books in Order

The Arcadia Project is urban fantasy with one foot in Hollywood and the other in fairyland. A secret organization manages the traffic between Los Angeles and Arcadia, a parallel world filled with beings out of myth and folklore. The people doing that work are not polished superheroes. They are damaged, strange, capable, and often hanging on by a thread.

At the center is Millicent Roper, usually called Millie, a former filmmaker, suicide attempt survivor, double amputee, and woman living with borderline personality disorder. When Borderline begins, Millie is recruited because she knows how to read people, spot performance, and keep moving when everything feels broken. Her voice gives the series its shape. She is funny, suspicious, sharp, and often much harder on herself than anyone else is.

This is not a chosen-one story.

A lot of the tension comes from work. Each book has a strong investigation at its core, starting with a missing movie star who is also a Seelie nobleman. From there the problems get bigger: impossible crimes, ghostly fallout, secret agendas inside the Project, and a widening split between Arcadia offices. By the time the trilogy is in full motion, the series has grown from hidden-world mystery into something closer to magical political crisis.

Los Angeles really matters here. Baker uses the city as more than backdrop. Studio politics, celebrity culture, and the strange logic of image management all blend neatly with fae glamour and court intrigue. That gives the books a different feel from more generic urban fantasy. They are noir-ish, funny, and a little jagged, but they are also very interested in performance, power, and the stories people tell to control one another.

The supporting cast does a lot of heavy lifting. Millie works with other Arcadia agents, handlers, and supernatural players who all want something, and almost everyone is carrying private damage. Some relationships grow into a rough found family. Others stay tense, brittle, or transactional. The books are good at letting alliances shift without turning everyone into a simple villain or hero. Either way, the series remembers that danger leaves marks, and that trust is never simple.

What really sets the series apart is how it treats disability and mental illness as real parts of life without making them the whole point. Millie's physical disability and borderline personality disorder shape the way she moves through the world, but they are not there to win pity. The books are fast, twisty, and full of fairy politics, yet they keep coming back to shame, loyalty, survival, and the basic question of who gets believed when things go wrong. There is humor in the middle of the darkness, and plenty of strange workplace energy too. If you want urban fantasy with sharp dialogue, messy people, and a very specific Los Angeles mood, start with Borderline and keep going through Phantom Pains and Impostor Syndrome.
