Krista Hart, editora de la gaceta para damas londinenses De corazon a corazon, no teme escribir sobre temas tan impopulares como la reforma social, ganandose una ferrea oposicion que supone un peligro para su reputacion e incluso su seguridad. Cuando se encuentra con un guerrero vikingo encerrado en una jaula como si fuera una atraccion de feria, Krista exige su inmediata liberacion. Aunque se dice a si misma que liberar a Leif Draugr es simplemente lo correcto, no puede negar la atraccion que siente hacia el, especialmente despues de que su padre lo transforme en un ""perfecto"" caballero ingles. Pero las amenazas anonimas que Krista recibe desde hace tiempo se vuelven mas agresivas, y es Leif quien debe protegerla de los que desean silenciarla... Corazon leal es el primer libro de una nueva serie de Kat Martin, cada volumen de la cual puede leerse de forma independiente. / To escape her life of poverty as a tenant farmer's daughter, Ariel Summers made a bargain with the devil--she would become the Earl of Greville's mistress in exchange for the schooling and refinements of a lady. But she couldn't foresee the earl's timely death, or her own disturbing attraction to his bastard son and heir, Justin Ross. Justin never meant to demand payment from the tempting young woman his father had so callously planned to ruin. But her innocent allure provoked his ruthless nature and he vowed he would have her in his bed. Seduction was his plan, but Justin never suspected Ariel's innocent passion would awaken emotions he had long believe dead. Now mistrust and betrayal threaten the fragile happiness the two of them have found, and Justin must convince. Ariel he isn't the heartless man she believes.
