In "Witchful Thinking" (£13) by Celestine Martin, charms and magical beings are the norm in the mystic seaside town of Freya Grove. High school teacher Lucy finds herself suddenly under a particularly tricky spell, which won't allow her to say no to anything. Complicating matters further is the return of Alex, her high school crush (and a merman) who is struggling with a hex on his own house, and he needs Lucy's help to lift it.
