Query: True sexy romance with mystery and suspense

One of Lisa Kleypas best. The book was filled with suspense and intrique, yet surpass its role as a true romance novel. The chemistry between Addie and Ben was passionate, sensitive and mature. The twists and mystery of the plot was well thought-out and plausible. Overall, it was an exceptional romance amongst romance novels. Thank you, Lisa!
