Tom Robbins is the absolute master of the mind tickling metaphor and of rolling up philosophy into the guise of a fun, sexy romp. At least usually. In this book, however, it's as though he has lost patience with being too clever or has forgotten that Buddhist life-flow style which allowed it to roll out as an underlying message. Here you'll get the philosophy spelt out by one of the heroes very directly. It's as if Robbins is leaving a simplified decoder for readers who lacked the sensitivity to find the same messages more subtly layered beneath the apparent action in more deeply satisfying previous works (most magnificently Jitterbug Perfume). It's Robbins for beginners - and given the backward forms of formula religious dullardism sweeping the western world he's probably wise to do this - and maybe open a few eyes for whom the 'real' Robbins is simply a whole quantum beyond their experience.
If, on the other hand you were already in tune with the mind-bendingly brilliant thoughts behind Jitterbug Perfume, this is not going to appeal quite as much.... and you might ask for those beetroots over old Tanuki.
