Giz is a rhesus monkey and he's full of big questions like what's on the other side of the fence.

Living in a zoo enclosure with the rest of the tribe, Giz is desperate to find out what happens in the land of humans.

Then, out of the blue, a newcomer arrives. Skink is an outrageous, fast-talking monkey who's had time in a lab cage, a pet shop, and a circus.

Full of mischief and fun, he helps Giz escape and together they try to find out more about where they come from - and decide where they're going to end up.

Paul Shipton is the author of the massively popular "Bog Muldoon" books.

Like "Animal Farm", this is a book that explores big themes through animals: social order, animal rights, bullying, and self-realization.
