The reading experience
Why it stands out.
Linus follows rules for the Department in Charge of Magical Youth until a classified assignment sends him to an island orphanage. The children and their caretaker test the assumptions behind his professional distance.
The book is an adult crossover novel, not middle grade. Its gentle style and child-centered premise do not change the intended audience, and its strongest match signals are character, hope, and found family.
