* "Placing elements of a locked-room mystery and an original magic system within the familiar trappings of a school for magic, this is a no-holds-barred tale of revenge, atonement, and the pursuit of justice set in a world diverse in skin color and social classes. Ren is a protagonist for the ages: equal parts smart, calculating, and ruthless, forming a lethal package as an avenging angel. Truly fantastic."--Kirkus Reviews, starred review
