Best-selling author Chelsea Clinton will present her new children’s book, Don’t Let Them Disappear: Twelve Endangered Species Across the Globe, at a special event and book signing May 23, 2019 at the San Diego Zoo.

A huge celebration took place at UCLA Mattel Children’s Hospital earlier today (March 7, 2019), complete with San Diego Zoo Safari Park animals—including a tamandua, a sloth, and a kinkajou—and a 15-foot-long lion puppet, and flamingo and giraffe puppets from the San Diego Zoo!
