I like the idea of how the road trip will explore the relationship between the two sisters, Tina and Lottie. Underneath the sibling rivalry, you sense there's affection, loyalty, support...and shared grief. That the pre-wedding road trip comes with the test of saying yes to any challenge is an interesting notion. I wonder if it will involve the man deliciously described as an 'athletic but debonair Cary Grant'? I have to say, however, that the book is probably not quite my type of read.
