Without this review (or the opening two paragraphs) I wouldn't have read this book:
3.5

This book was a ridiculous premise and winds up being pretty stupidly cute. It actually worked, where Isabelle could come across as a bit vapid or shallow when pitted against the guarded Millie, here she comes across as vulnerable, sweet and free-spirited--kind and loving too. She was delightful and slightly uncomplicated (though not 'simple'). Which made the novella just right for her. It's definitely quick, yet somehow convincing.

However, I suggest you just read Wollstonecrafthomegirl's review. ( )

I loved this novella from the Fitzhugh Trilogy. I really had my doubts when I realized it was about "the other woman" in Fitz' life (from Book 2 in the trilogy.) But Isabella won me over! She is delightful! Had a wonderful sense of humor and personality. The story of meeting Fitz' lookalike and how, then their ensuing friendship was marvelous. I loved him as well! I really, really enjoyed this, a pleasant surprise! ( )
