Angels on Crusade — Samantha Winston

A condemned criminal in the far future is sent to the past to try to save the crown of France. Isobel was a carefree student one day, and in prison the next for the accidental murder of a child. Her fate, life in prison. But she's offered a way out - through time. The crown of France is in peril. A young boy, who never should have left Paris, has gone to join the ill-fated 8th Crusade. Isobel's task is to talk young Jean de Bourbon-Dampierre out of joining the Crusade so that he can sire a dynasty. Isobel chooses to go back to the twelfth century, although she knows she will be left to spend the rest of her life there. At least it will give her a chance to redeem herself, she believes. If she fails...it's erasure and certain death, and someone else will be sent. In any case, she will never see her own time again.
