From Publishers Weekly
Two strong-willed people learn that they do not always know best in Farr's formulaic romantic comedy, which is ostensibly set in the 19th century. When Delilah Chadwick learns of her father's hasty plans to remarry, she becomes concerned that he is being manipulated by a scheming harpy, especially since the hitherto pragmatic Sir Horace hasn't even given his daughter a chance to meet his fiancee. Lilah reluctantly joins forces with Adam "Drake" Harleston, the earl of Drakesley, who is convinced that his young cousin has been seduced by the much older Sir Horace. Together they journey to Wexbridge Abbey in the hopes of stopping the impending nuptials, but their partnership is not at all harmonious. To the reader's frustration, Drake and Lilah manage to engage in a battle of wills over the smallest of decisions, even as they are irresistibly drawn to each other. Although occasionally interspersed with witty dialogue, the book on the whole misses its mark. Drake comes across as overbearing, and Lilah is given to childish tantrums. At one point, she even exclaims "I wish to return to Wiltshire with Papa and go on just as we always have!" It's clear that Drake and Lilah are meant for one another, but there's little incentive for readers to stick with the story and see that they get it right.

From Booklist
Lilah and Adam, ninth Earl of Drakesley, have only two things in common. The first is that Lilah's father and Drake's cousin plan to marry, a marriage they rush to London to stop, meeting along the way and discovering their mutual mission. The second thing they share is their forceful, overly assertive personalities, the results of having been raised with no one to gainsay their every wish. Constant bickering ensues when each finds that the other is not responding as most do to their habit of riding roughshod over any and all obstacles. In pursuit of their common goal, they must work together: and, in spite of finding this difficult, the passion that results from their close proximity is as forceful as their personalities. Farr's headstrong characters aren't terribly likeable at first, but this romance's appeal grows as the reader gets past Drake's and Lilah's egocentrism. Maria Hatton
