Christi Caldwell’s THE DIAMOND AND THE DUKE features Wesley Audley, freshly home after nearly dying in battle, and Ellie Balfour, the woman who has secretly loved him for years. As Ellie helps Wes remember the man he was while he recovers physically, they begin to grow closer. Unfortunately for Ellie, there is still the matter of the letters she wrote to Wes pretending to be his former love hanging between them.    I loved the first half of this book! Caldwell does a fantastic job of portraying someone in the throes of PTSD. Unlike many romances that promise a grumpy hero and don’t deliver, this one does. Wes is a very bitter man for much of the first half of the book, and I appreciate that he wasn’t over it within a chapter or two. However, Ellie and Wes did rehash the same conversation multiple times in the first half to the point it got a little tedious. The second half was forced to tie up all the loose ends from the first, and it was a bit chaotic. It made it hard to really enjoy the second half, especially when compared to the first.    I really like both Wes and Ellie. Ellie’s strength as she helps Wes overcome his demons was wonderful to read about. I love that she was the only one with enough courage to face him down. Even in his worst moments, there is still humanity in Wes, and the man he was shines through at times.    I did find myself wishing I had read the previous book to see what exactly Ellie had done rather than just reading about it here, but it is explained pretty thoroughly.    While the first half of this title is great, the plot struggles in the second half with too much going on. The characters, however, are delightful throughout. I will definitely be checking out the next title in this series.
