'Coming Home' by Michael Morpurgo

A plucky little robin sets out on an epic journey. Through dark forests, driving rain, clapping thunder and flashing lightning. Across frozen wastes, huge mountains and stormy seas he flies. And all the while he's dreaming of home. Of her. But will he ever get there? Find out in this wonderfully lyrical Christmas story from the brilliant Michael Morpurgo, with stunning illustrations by Kerry Hyndman.
