It's a tall order in this day and age to write a book about a young boy in magic school without being held to the Harry Potter standard, but that's exactly what Black and Clare attempt in their first collaboration (and Clare's first middle-grade offering). The premise is simple: 12-year-old Callum Hunt has been warned about the dangers of magic for as long as he can remember by his father, a former mage, who blames the Magisterium, a magic academy, for the death of his wife. Despite Cal's best attempts to fail the entrance exam into that academy, his inherent magical ability gets him accepted, and he begins the first of five years of his training. Occasional comparisons to Harry Potter are inevitable, but Cal isn't the Boy Who Lived though his friend Aaron might be d the Magisterium isn't Hogwarts. Expectations are bound to be high for this powerhouse duo's first cowritten effort, and although it doesn't quite live up to the authors' respective works (Black's Doll Bones was a 2014 Newbery Honor Book), and there are several missed opportunities, the end offers a few intriguing twists and perspectives that hint at what's to come in the next installments. And with four Magisterium volumes still in the works, Black and Clare have ample time to hit their stride as a team. HIGH-DEMAND BACKSTORY: The six-figure initial print run may still be shy of the demand from the fans of these two wildly popular authors.

The lone survivor of a horrific massacre as a baby, Callum Hunt is found with a curious note from his mother: "KILL THE CHILD." His mysterious past and inexplicable powers seem to mark Callum as the classic child of destiny, but the authors stand that trope on its head. With a clever ending twist, this series seems poised to attract a loyal following.

Set in a magic-inflected version of the present-day U.S., this first title in the Magisterium series combines the talents of Black (Doll Bones) and Clare (the Mortal Instruments series) in a thrilling coming-of-age story that embraces fantasy tropes while keeping readers guessing. Twelve-year-old Callum Hunt has been raised to distrust magic. Mages killed his mother, and his father has warned him that the Magisterium, a school where young mages are trained, is a deathtrap. Callum-s attempts to fail the entrance exam go awry, and he is chosen to apprentice under Master Rufus, along with fellow students Aaron and Tamara. As Callum, Tamara, Aaron, and their classmates embark on their first of five years of schooling, Callum realizes how little he knows of his own heritage. The strange, subterranean Magisterium is vividly rendered, and a string of ominous revelations will leave readers eager for future installments. Fans of both authors will enjoy getting to know this well-rounded cast in the first steps of their adventure. Ages 8-12. Agent: (for Black) Barry Goldblatt, Barry Goldblatt Literary; (for Clare) Russell Galen, Scovil Galen Ghosh Literary Agency. (Sept.)

Gr 5-8 All his life Callum Hunt has been warned by his father that practicing magic is a guaranteed death sentence, the only certain way to make sure he doesn't reach his 18th birthday. When Call is summoned to attend the entrance exams for The Magisterium, a more-sinister version of Hogwarts School of Witchcraft &; Wizardry, he promises his father he will deliberately fail the test to avoid the dangerous lure of magic school. Unfortunately, magic is in Call's blood, and though his permanent limp and sarcastic attitude do not appear to serve him well during testing, he is selected with two other "Iron Years" to be a pupil of the greatest mage of all, Master Rufus. Black and Clare have created a unique world in The Magisterium, adroitly sidestepping reader fatigue with the many post-Harry Potter "magical academy" fiction series. The underground school's labyrinthine tunnels, mysterious caverns, and strange rivers are an alternately wondrous and creepy setting for this hero's quest. The diverse main trio's multidimensional portrayals leave aside easy characterizations in favor of complex motivations which add depth to each character. Best of all, a late-stage reveal of the novel's true hero and villain neatly turn fantasy tropes on their heads. Elisabeth Gattullo Marrocolla, Darien Library, CT
