The Spellshop by Sarah Beth Durst follows Kiela, an introverted librarian who escapes a burning imperial library with her sentient spider plant assistant and a cache of forbidden spellbooks. Hiding on the remote island where she grew up, she tries to rebuild a quiet life, only to be continually interrupted by a persistent, kind neighbor who insists on helping her settle in. To support herself, Kiela turns to making jam and, with cautious use of illicit magic, begins selling discreet enchantments alongside her preserves. This cozy fantasy romance centers on small-town rhythms, gentle supernatural elements, and a reserved but strong female protagonist learning to trust both community and love.

In Ninth House, Leigh Bardugo shifts to adult dark fantasy with a supernatural mystery set amid Yale’s secret societies.
