Books like Satin Ice (The Delaney's, the Untamed Years II) by Iris Johansen

TO SAVE THE CHILD ETAINE, SILVER AND NICHOLAS MUST BATTLE THE PRINCE OF DARKNESS BUT WILL HIS DEFEAT COST THEM THEIR LIVES? In the glittering, endless white nights of a Russian summer Silver Delaney felt isolated, alone, even in the shimmering crystal palace that was her husband's home. Her magnificent Cossack prince still made her burn with hunger, ache with need, but Nicholas seemed unwilling to admit that desire still held him captive. If she was his firebird, his destiny why didn't he touch her, caress her, command her? She felt like a wild thing seeking refuge from a storm, but was Nicholas the storm, or the refuge? Gowned n sate, arrayed n an empress's rubies, Silver dazzled the Tsar's court, but found powerful enemies in Nicholas's mother and the villainous Monteith--and suspected a terrible betrayal. Nicholas tried to heal Silver's pan, but cherishing her meant opening old wounds of his own. Could he persuade his wild angel that once a firebird summoned her lover, he would forever follow her to the ends of the earth? THE DELANEYS: THE UNTAMED YEARS II
