I had been looking forward to Serena Valentino's novel Mistress of All Evil: A Tale of the Dark Fairy for so long, not only because I very much enjoy her Disney Villains novels but also because Maleficent is my favorite of the Disney Villains. Mistress of All Evil is the fourth installment in Valentino's Disney Villains series, preceded by Fairest of All: A Tale of the Wicked Queen, The Beast Within: A Tale of Beauty's Prince, and Poor Unfortunate Soul: A Tale of the Sea Witch. While Fairest, the first in the series, remains my favorite, Mistress is undoubtedly my second favorite. The novel takes us back to Maleficent's childhood and teenage years, leading us up to what eventually causes her to become the eponymous Mistress of All Evil. (As readers of previous novels of the series can probably surmise, Valentino's original Odd Sisters are involved, but so are several other characters.) There is definitely a lot of room for sympathy for Maleficent because as is the case with Fairest, this novel reveals to us that not everything that we see in the Sleeping Beauty film is as we had thought because not everything is within Maleficent's control. Valentino crafts a much different story than Linda Woolverton does in her 2014 Maleficent film starring Angelina Jolie, and each story has its strengths. Valentino, for example, gives us more about Maleficent's youth, and her novel also takes place in the same universe as the classic Sleeping Beauty film (whereas the Angelina Jolie film cannot possibly take place concurrently with the classic animated film for many reasons). The Angelina Jolie film, however, is much more focused on Maleficent as a character, and that Maleficent is a much more independent and autonomous character. Something that has always bothered me about the Angelina Jolie film, however, is that it offers no explanation as to why Maleficent's parents would give her a name that basically means evil, but Valentino does explain the origin of her name. I think that one of the main aspects of Mistress of All Evil that bothers me a bit (which I admit is a bit nitpicky) is that Fauna, the good fairy dressed in green, is depicted no differently than either of the other two fairies. In Sleeping Beauty, however (and, for that matter, in Liz Braswell's novel Once Upon a Dream), Fauna is depicted as the only one of the three good fairies who seems to harbor some compassion for Maleficent, first by suggesting that they try to reason with her (which, according to this novel, might have possibly worked) and then by suggesting that Maleficent is evil because her life is void of love. In Mistress of All Evil, however, Fauna is just as petty and as cruel to Maleficent as Flora and Merryweather are. Aside from that, I really don't have many complaints. Mistress of All Evil reminds me a great deal of Gregory Maguire's novel Wicked, which is a retelling of The Wizard of Oz from the perspective of The Wicked Witch of the West. Both novels have a lot in common; both Elphaba (The Wicked Witch) and Maleficent are born with green skin and other physical oddities that cause them to be feared and hated by their societies, and both are looked after by maternal figures known only as Nanny. I don't know if the similarities and parallels are intentional on Valentino's part, but they are definitely there nonetheless. I also much enjoyed all of the references and connections to other Disney films. Both Snow White and Queen Grimhilde (whom Valentino finally names) return. The Beast is mentioned several times, and the novel begins directly following the aftermath of Ursula's death. Hades is mentioned more directly than he was previously in the series. Cinderella is once again mentioned, and her Fairy Godmother is even a character in this novel. We briefly meet the Blue Fairy, and Pinocchio is consequently briefly mentioned. This idea that all of these Disney films are connected and take place in the same universe is one aspect of this series that I absolutely adore, and although she isn't necessarily one of my absolute favorite Disney Villains, I am definitely looking forward to Gothel (from Tangled)'s story, titled Mother Knows Best, which is expected to be released next summer.
