This is very much a book of two halves and if I judged it by the first half, I would be flouncing the entire book and giving it a 1 star review. Luckily, it does get better. The problem with the first half of this book is that in order to make the heroine, Tally, seem innocent and naive and kind, Graham has populated the novel with a series of vile characters that take advantage of Tally. I know it's supposed to show the difference between the 'good' poor and the 'selfish' rich, but as the hero, Sander, comes amongst the rich, it doesn't really make you think that well of him. The other irritating thing about this first half, is the relationship shown between Tally and her half-sister Cosima. Cosima is a vile, spoilt character, and yet because Tally keeps reflecting that her sister is young and doesn't know better, that excuses her behaviour. It doesn't, and the scene where she drugs Tally so that she can spend uninterrupted time with her boyfriend is just appalling. If it was me, I would be swearing and cursing up a storm as its a massive violation of trust and your person, yet by the next chapter the two women are back to being relatively friendly again. It's a horrible relationship and not one that is excused by any kind of naivety. It made me think a lot worse of Tally that she would work to keep that relationship going, even when forced to play her sister's PA because Cosima refuses to acknowledge that they're related.
Luckily, the last half of the story was much better, developing the romance between Tally and Sander and how they relate to each other. By chance, I'd actually read the second part to this story, Bride for Real, before I read the first, so I knew where the relationship ended up but not where it started so it was nice to see them together, even though some parts were a little sad to read, knowing where they end.
It's unfortunate really that if I'd flounced the book like I wanted to at the start then I wouldn't have gotten to enjoy the second half. And for that reason, I'm giving The Marriage Betrayal 2 stars.
