Even though Delphinia Baker has never had anyone she can call her people, she has always had her grandmother—best friends since forever, that’s enough. Besides, having no roots just makes it that much easier when you have to move again. All of that changes, though, when Gramma falls ill and Del is sent to stay with her great-grandmother. And when Nana Rose starts talking about the school she runs dedicated to their family’s traditions—something called “conjure magic”—Del knows she’s in for a weird, awkward summer. That is, until the magic turns out to be real. Soon, Del is surrounded by teachers who call themselves witches, kids with strange abilities, creatures and ghosts who can speak to her. She has a hundred questions, but one more than any other: Why didn’t Gramma ever tell her about her family, the island, this magic?
