Witches of the Island Books in Order

On paper, Witches of the Island is Katie McGarry's move into adult fantasy romance. In practice, it still feels like a McGarry story, just with witches, fae, demons, and prophecy added to the emotional punch. The series begins with A Wicked and Beautiful Garden, where Cassie Strega is living a mostly quiet life as a midwife and trying not to ask too many questions about the strange gifts she has always carried.

That quiet life does not last. Cassie learns she comes from a line of witches, and the return of Orion, the fae warrior she once loved and thought she had lost, pulls her into a hidden conflict that has been moving behind the human world all along. Their history matters as much as the magic does, because this is just as much a second-chance love story as it is a fantasy adventure.

The romance is the engine.

Across the trilogy, Cassie is not simply learning spells or discovering who she is. She is trying to survive a war shaped by prophecy, old loyalties, and the question of whether love can change the future. Orion is caught between duty and devotion. Cassie is caught between ordinary human life and a supernatural role she never asked for. Around them are witches, fae allies, dangerous enemies, and a child whose existence raises the stakes for every side.

The setting moves between small-town everyday spaces and a much stranger magical world, which gives the books a strong contrast. One scene can feel domestic and grounded, then the next opens into fae politics, demon power struggles, or a chase tied to ancient promises. McGarry keeps the emotional focus close, though, so even when the mythology gets bigger, the story stays centered on trust, betrayal, and the cost of choosing one life over another.

It gets bigger fast.

If you are wondering what kind of reading experience to expect, think paranormal romance first, with fantasy stakes rising from book to book. The trilogy has soul bonds, curses, prophecies, enemies who are not always what they seem, and a strong thread of found family. It also follows one continuing arc, so this is a series best read in order, starting with A Wicked and Beautiful Garden and moving straight into A Stormy and Sultry Sea. Readers who like emotionally intense couples and magic with real consequences will probably feel at home here.
