Silent to the Bone

Blurb

Silent to the Bone is a novel by E. L. Konigsburg for the "middle ages" or for young adults. It is a companion to The Outcasts of 19 Schuyler Place, a fifteen-years prequel published four years later.
Acting as a best friend, therapist and detective, young Connor Kane with his adult half-sister "uncovers a complex, multilayered tale of human desires, adolescent confusion, and a touch of menace". Part detective story, some reviews portray it as mystery fiction primarily. It has been recommended for ages 10 to 14.
