Ce livre est la transition parfaite entre la saga Harry Potter et la trilogie des Magiciens. [...] En plus de tout ça, on trouve, en vrac : des références culturelles géniales, l'utilisation de la technologie par les sorciers, une guerre inter-espèces, la lutte contre le sexisme, des super-héros discrets, quelques insultes bien envoyées [...] un roman one-shot à lire absolument pour tous ceux qui aiment la magie, les histoires de grands ados (les héros sont majeurs) et, ok, les histoires d'amour un peu.
