His Castilian Hawk (The Castilian Saga Book 1) by Anna Belfrage

For bastard-born Robert FitzStephan, being given Eleanor d’Outremer in marriage is an honour. For Eleanor, this forced wedding is anything but a fairy tale. Robert FitzStephan has served Edward Longshanks loyally since the age of twelve. Now he is riding with his king to once and for all bring Wales under English control. Eleanor d’Outremer—Noor to family—lost her Castilian mother as a child and is left entirely alone when her father and brother are killed. When ordered to wed the unknown Robert FitzStephan, she has no choice but to comply. Two strangers in a marriage bed is not easy. Things are further complicated by Noor’s blood-ties to the Welsh princes and by covetous Edith who has warmed Robert’s bed for years. Robert’s new wife may be young and innocent, but he is soon to discover that not only is she spirited and proud, she is also brave. Because when Wales lies gasping and Edward I exacts terrible justice on the last prince and his children, Noor is determined to save at least one member of the House of Aberffraw from the English king. Will years of ingrained service have Robert standing with his king or will he follow his heart and protect his wife, his beautiful and fierce Castilian hawk?

In the Shadow of the Storm: The King's Greatest Enemy #1 by Anna Belfrage

Adam de Guirande owes his lord, Roger Mortimer, much more than loyalty. He owes Lord Roger for his life and all his worldly goods, he owes him for his beautiful wife – even if Kit is not quite the woman Lord Roger thinks she is. So when Lord Roger rises in rebellion against the king, Adam has no choice but to ride with him – no matter what the ultimate cost may be. England in 1321 is a confusing place. Edward II has been forced by his barons to exile his favourite, Hugh Despenser. The barons, led by the powerful Thomas of Lancaster, Roger Mortimer and Humphrey de Bohun, have reasons to believe they have finally tamed the king. But Edward is not about to take things lying down... Adam fears his lord has over-reached, but Adam has other matters to concern him, first and foremost his new wife, Katherine de Monmouth. His bride comes surrounded by rumours concerning her and Lord Roger, and he hates it when his brother snickers and whispers of used goods. Kit has the misfortune of being a perfect double of Katherine de Monmouth – which is why she finds herself coerced into wedding a man under a false name. Domestic matters become irrelevant when the king sets out to punish his rebellious barons. The Welsh Marches explode into war, and soon Lord Roger and his men are fighting for their very lives. When hope splutters and dies, when death seems inevitable, it falls to Kit to save her man – if she can. In the Shadow of the Storm is the first in Anna Belfrage’s new series, The King’s Greatest Enemy, the story of a man torn apart by his loyalties to his lord, his king, and his wife.
