finished the book yesterday (i tore through it, i couldn't put it down). i LOVED it. the characters were great (i must admit to absolutely falling in love with Rachel. god what a charming character even though she's speechless for 99% of her appearance), the pacing was great and the ending was a pleasant surprise. i gave it 5 stars on amazon.
i think this book contains the first graphic, yet not graphic sex scene i've ever read lol. it wasn't filthy, overly descriptive or corny/tacky yet wasn't bland nor innocent either. i think you found an unusual middle ground. to be frank it was far more erotic than most 'erotica' i've seen, maybe because i absolutely adored the characters by that point and was actually happy for them.
i don't think i've ever begged an author to keep writing but please keep writing.
