For anyone who has read Niven and Pournelle's Inferno this book will cover familiar territory. This is a great page turner covering the later exploits of Allen Carpenter ex-author and now guide to potential escapees from Hell. It follows the familiar route map of Dante's Hell but with enough twists to keep it fresh and some stunning conceits make it a worthy adjunct to the earlier volume
If you know and like Carol Klein's Grow Your Own Veg (Rhs) then this new book is reasonably familiar territory. The main differences are that this does not (yet) have a TV series tie-in and a lot more of the text reads dryly as if it was written by earnest people from the RHS.
It is a good introduction - It loses 1 star from me as it does omit Rhubarb !!
