What Marcy is looking for
Marcy is never looking for what is currently trendy because it will soon be gone. She’s interested in books like The Evolution of Calpurnia Tate, which transcend the moment. Since she also works in the adult space, Marcy is also looking for books that can cross over from both middle-grade and YA. Marcy is not looking for middle-grade at this time. For YA, she’s only interested in contemporary, historical, and thriller/suspense.
