When the ice starts melting, it’s time for the yaks to move on and find a new mountain. Gertie’s mum tells her that home is about more than the things that you pack, but Gertie’s not so sure. She tries to squash and squeeze everything they own onto her sled. But, oh no! It seems she’s left behind the most important thing of all . . . her baby sister, Dotty!
