'Ape House' is an ambitious novel in several ways, for which it is to be admired, and it is certainly an easy read, but because Gruen is not quite prepared for the philosophical implications of her subject, it is not as deeply involving emotionally or as interesting thematically as it could be.
'Lean on Pete' is the story of a boy and his horse, but it is never heart-warming - it ranges in tone from desperate to merely painful - and, while fascinating, it is never entertaining or redemptive. But if you want an unadorned portrait of American life (at least in some places) at the beginning of the 21st century, this is the book for you.
Why are we reading a Shakespeare play or 'Huckleberry Finn?' Well, because these works are great, but they also tell us something about the times in which they were created. Unfortunately, previous eras and dead authors often used language or accepted as normal sentiments that we now find unacceptable.
