Widowed for the second time aged thirty-one, Katherine is obliged to return to court but, suspicious of the aging Henry and those who surround him, she does so with reluctance. Nevertheless when she finds herself caught up in a passionate affair with the dashing and seductive Thomas Seymour, she believes she might finally be able to marry for love. But her presence at court has attracted the attentions of another. Captivated by her honesty and intelligence, Henry Tudor has his own plans for Katherine and no one is in the position to refuse a proposal from the king. With her charismatic lover dispatched to the continent, Katherine becomes Henry's sixth wife. Passionate about religious reform, and ever aware of the fates of his previous queens, she must draw upon all her instincts and intellect to navigate the treachery of the court. With the Catholic faction once more in the ascendency, reformers burned for heresy and those around the dying king vying for position in the new regime, her survival seems unlikely and yet she has still not quite given up on love.
