The girls of W.I.T.C.H. know their stuff when it comes to friendship - after all, their friendship results in some pretty powerful abilities. In Friends, the Guardians take on the subject of friends and help the reader learn just how important good friends can be.
Guide to Friends, unlike most W.I.T.C.H. media, does not include a story but includes characters thoughts on friendship, diary extracts from the girls diaries, scripts of conversation between the girls, "agony aunt" style columns run by the girls, general advice on friendships, and quizzes.
