I’ll never forget the first rejection I received from a literary agent. “This is a great premise,” she told me, speaking of my then-unpublished debut novel, The Witches of Willow Cove, “and the story is fun and fast paced. But what’s holding me back here is the age range of the book. I found myself wishing the characters were younger—11 or 12—and I wish this novel were more firmly rooted in the middle-grade realm, sticking to middle-grade topics, rather than skewing older.”
