The road to somewhere - Helen Armstrong

When Cow hears that she is going away in a truck to never-come-back, her old friend Ratty knows he must help her escape. They are joined by Woolly, the tough fierce lamb who doesn't want to be lamb chops any more than Cow wants to be beef stew.

As the three friends set out bravely into the unknown, they meet terrible dangers and kind strangers
and some who are not to be trusted. Their amazing adventures require Cow and Woolly to show a determination and resourcefulness they have never needed before, while Ratty's quick wits see them through.
