In Book 4: The Baboons, Casper’s barely woken up (in a tree, again!) when she’s flung headfirst into the chaos of a noisy troop, two wild twins, and a whole heap of monkey business. But when a baby baboon goes missing – and is found cradling a leopard cub – everything changes. The birds go quiet. The grass stands still. Old enemies gather, ready to fight to the death.​

Casper is just one small cat. But with a little courage – and a lot of heart – she learns that even the smallest step can start something big. Because sometimes, changing the world means starting with your own little corner of it.
