Sue Dalston is a fantastic characterisation - I don't doubt there are plenty of real life Sue Dalston's out there. Martina writes about her with such clarity and realism that I really feel she must personally know a Sue Dalston. You get drawn into Sue's life and realise how she is trapped. You really end up understanding why she behaves as she does.
One more slight criticism of this otherwise five star read is that all through the book Sue's mother is a total scumbag, yet towards the end of the book she miraculously discovers maternal feelings. It's as though Martina wants to tie up all the loose ends nicely and provide a nice happy ending. The family party towards the end of the book - with all the family members getting along and enjoying themselves together just seems unreal and spoils it a bit. Memo to Martina : your books are based on realism, real life doesn't have happy endings all the time.
The book is definately a page turner and Martina knows how to work the reader. Agripping read to the end and you won't be disapointed by the twist in the tale as you really feel that it could happen. Very cleverly written.
