A variety of Seeker series books by Erin Hunter. Suitable for ages 8-12, though young teens would probably enjoy them too. Set in the near future, the protagonists are 4 bear cubs. 'The books are set a little way into the future, where the lives of all wild animals have been severely compromised by human encroachment on their habitat and natural sources of food. All these three kinds of bears have forgotten how to be truly “wild”, which is a lesson they must learn as they travel from their BirthDens on the journey of a lifetime.'
I think there's 2 complete sets and a manga style one, 13 in total.
