I haven't read them myself but my son has and has said he was disappointed.
They are aimed at children after all - if you are used to 'heavier' reading you might feel that you are being 'condescended to'. (like being told what to do by teacher) I dont think they will become classics , like The Children of The New Forest, which I still remember from my childhood -stirred my 1st interest in history. The good result is that more children have discovered the joys of reading which is a great achievement.
