Misbegotten — Tamara Leigh

PASSIONATE BETRAYAL
Tricked out of his rightful inheritance by his treacherous half brother, baseborn knight Liam Fawke swore to contest the claim of the young nephew who was now heir.

DANGEROUS DESIRE
Lady Joslyn was determined to protect her son from Liam's vengeance. But her resolve was no defense against the heated desires the ruggedly handsome warrior ignited--or the forbidden love no duty and honor could make her deny.
