After being expelled from a boarding school on Earth, Puck is headed to an alien planet, which humans call Aurora, where her parents, who are xenoanthropologists hoping to study the native Shoowa, await her arrival.

While aboard the spacecraft Cat's Cradle, she unexpectedly befriends an alien named Hush.

While aboard the spaceship, both Puck and Hush find themselves immersed in the mystery of lost objects and ghosts, and murder.

Kirkus Reviews called the novel "great fun," highlighting Klause's writing skills and discussing how she juggles the plot "with admirable aplomb while devising a poetically literal manner of speech for Hush, deftly creating memorable characters [...], writing wonderfully suspenseful scenes [...], and slipping in some thoughtful, quite beautifully written passages.

"[2] Publishers Weekly provided a more mixed review, first praising Klause for her "extraordinary job of imagining Hush's culture and his pain at having lost the artifact," then discussing the faulty plot and pacing: "It takes Klause almost half the novel to establish all the plot points needed to generate real suspense, and after that leisurely set-up, the author moves too quickly, blurring details and trampling on what could have been exquisite moments.
