Sofia has never felt special. Not at school, or with her track team, and especially not since she's become sick.

She's always been different, but this doesn't make her stand out . . . it's makes her invisible. Then something special lands right in Sofia's lap. An ancient book that serves as a portal for the Greek philosopher, Xeno, one of Aristotle's lost students. Sofia has been chosen to be the next Guardian.

Suddenly Sofia is not only trying to survive middle-school cliques and first crushes, she's in charge of protecting grotesquely beautiful, lonely monsters that have roamed the Earth for centuries. Drawn into Xeno's violent and unpredictable world of mystery, Sofia learns that loving outsiders has a price.

"While the fantastical elements are compelling, it's the real-world situations that make this book stand out. . . a perfect recommendation for introspective kids who feel like outsiders."--SLJ

"Garrett's prose, frequently poignant and sophisticated, is punctuated with wry humor."--Kirkus

"The oft-used concept of finding one's true self is employed here in a uniquely imaginative way, complete with occasional black-and-white illustrations. An appealing tale for readers dealing with their own insecurities."--Booklist
