Endangered is a thrilling story of a teenage girl caught up in an African civil war that starts while she is taking care of bonobos in her mother's sanctuary. It's heart-warming, political, and enlightening. So, naturally, it was nominated for a National Book Award. Eliot Schrefer wrote an amazing novel.

This cover needed to be as dark and intriguing as the story. It was created using a stock image from Anup Shah/Getty images.

When it came time for a paperback edition of Endangered, enlarging the elements seemed fitting to help the cover stand out a little more and make it feel like the big book it is. Again, the bonobo photo is Anup Shah/Getty images. 

Schrefer's next novel, this time about a boy helping study chimps in Gabon, called for a similar look that would still allow for differentiation between the two stories. (The cover photos are from Nigel Pavitt/Getty Images and Mike Lanzetta/Getty images. The photoshop work was done by Blake Morrow.)
