Well it certainly did crack along at a read-in-one-sitting pace. I read it very quickly and was held till the end, despite finding it largely risible.
My main issues with it actually partly stem from the pace, I think - the whole thing is breathlessly teenage, reading like it was written in one big blurt and published as is, which meant that for me the characters were hopelessly two dimensional. It's as if the author thought 'what's the most extreme situation I can think of? I know - a rabidly religious zealot falling in lust with an atheist abortion facilitator. And get this - her mum is a lesbian and her best friend is gay! Watch the sparks fly!' There was no depth or believability to their relationship, they just seemed to lurch between bodice-ripping boning and storming off in a huff. The sex scenes made me hoot though 
It wasn't all bad - there was some good writing about Aggie's post-bereavement loneliness and Honey's horrible day to day life. I would have liked to see more of Honey, actually, she was a more well-rounded character and brought some much-needed balance to the lustapolooza. I also wish the anti-abortion protest plot had been developed more though, as it felt a bit tacked on for convenience's sake.
All in all (and despite how it may appear) I did enjoy reading it! It would be interesting to see how the author's work develops as she is clearly capable - she just needs to slow down a bit IMO.
