Since the death of her parents, dreams and the cruel whims of her guardian, Baron Pike, are all that are left to Lady Catheryn of Brezden.  Only her belief in the power of dreams gives her hope for the future.

Since his wife and son's deaths at the order of Baron Pike, Count Gerard of Reveur knows that dreams are nothing more than a childish fancy and believes only in the power of revenge.

Legend says that if a maid sleeps with a dream sachet made of the magical herb yarrow beneath her pillow, she will dream of her true love.  But Catheryn's dreams are not of love, they are of a dark and dangerous knight who seeks to destroy Brezden Keep and all she holds dear.

When Brezden is lost and Pike slaughtered by a frightening warmonger, Catheryn loses faith in the legend.  The legend lied—this man cannot be the true love promised her.  And when Pike's evil minion, Raymond de Brye takes up where his mentor left off, Catheryn is unwilling to trust in whims, or dreams again.  Now she seeks to vanquish the final threat to Brezden and herself.

Forced to marry Catheryn by the Earl of York, Gerard finds himself at odds with his new and unwanted wife.  She knows where the villain who carried out Pike's dastardly orders is hiding, yet refuses to divulge the information. 

When a traitor to King Stephen is discovered to be operating out of Brezden Keep, Gerard has little choice but to question his wife's loyalty.  Is she in league with the traitor de Brye? 

While the couple's relationship lacks trust, it does not lack passion.  They share a desire that burns hot between them. But is it strong enough to overcome doubt and distrust?  Can they build a marriage on passion?

Along with searching for the traitor who is wreaking havoc on Brezden, Catheryn and Gerard seek answers to these questions. By the time Catheryn realizes that Gerard is worthy of her trust, she's been implicated in a plot to smuggle supplies and funds to the King's rival.

Captured and held hostage at the earl's keep in Scarborough, Catheryn is shocked to find her enemy there too.  An enemy who takes her captive and holds her in a cave.

Gerard and his men rush the cave to rescue Catheryn.  When she sees the dark and dangerous knight from her dreams bearing down on her she knows for certain that the dream had not lied.  He had not sought her death, but her rescue.

Catheryn is safe and de Brye is captured and detained at Brezden.  A fight ensues leaving de Brye dead and Catheryn injured.  Waiting for Catheryn to awaken from a long, healing sleep, Gerard realizes that if he loses Catheryn, he loses everything—his heart, his soul, his reason for living.  Just as important he'll lose his newfound belief in dreams of tomorrow.       

When Catheryn awakens, Gerard presents her with a ring.  An emerald set in an intricately carved gold band.  A ring identical to the one the dark knight in her dreams wore as he charged toward her and Brezden.

The promise of the yarrow had been true.  Her dream had foretold not of death and destruction, but of rescue, of safety, and of love.
