Could this adventure possibly lead to a reconciliation between the two lovers and to the succession, yet again , of the swordThis adaptation of the forthcoming film The Legend of Zorro completes the circle of history established by Isabel Allende's new book exploring the birth, life and times of bon vivant Don Diego, the first generation Zorro, and by the 1998 blockbuster film Mask of Zorro which recounted the assumption of the mask by the equally dashing and principled second generation Zorro, Alejandro with the introduction of a possible third generation Zorro.

A prominent physician debuts as a gifted storyteller in Lie Still, a dazzlingly suspenseful and compulsively readable trip through the dark underbelly of the OR -- where reputations, careers, and lives are on the line. In a sleepy, small-town Arizona hospital, a thirteen-year-old boy lies in a coma after inexplicably suffering a cardiac arrest. His doctors are perplexed. Although emotionally disturbed Henry Rojelio was a frequent visitor to the emergency room -- often for bouts of asthma, but usually just for attention -- no one ever anticipated a battle with death. Surgical resident Malcolm Ishmail began his medical career months before at a busy Phoenix hospital -- a far cry from the small ER deep in the silent heart of the desert, where Henry Rojelio lies. There, Malcolm fell into a secret, exhausting affair with one of his professors, Dr. Mimi Lyle, a beautiful, charismatic brain surgeon who had subtle difficulties in the operating room. In a moment of weakness "Dreamy Mimi" confessed to him her failings as a neurosurgeon; Malcolm reported her to his superiors . . . and promptly lost his job. Now, miles away from Phoenix, Dr. Ishmail struggles to save his young asthmatic patient's life and his future as a surgeon. And with little time and few clues to the cause of Henry Rojelio's sudden collapse, the impressionable doctor wonders whether his former lover may have exacted a disturbing revenge.Rich in medical detail and written with stylish, razor-sharp action and dialogue, Lie Still is a gripping, emotional drama of human failings and devastating consequences that marks the debut of a remarkable new voice.
