Yours Until Dawn (Fairleigh Sisters #3), by Teresa MedeirosRead about the other entries on the list.
Gabriel Fairchild may be a hero, but the costs of valor are more than he can bear: has lost his sight, and the woman he loved. Darkness has descended on every part of his life, a darkness that even nurse Samantha Wickersham can’t lift. The nurse charged with caring for him, Samantha may be a woman, but she is no doormat, and refuses to let Gabriel wallow in self-pity. Eventually, Samantha determines that the key to healing Gabriel may not be trying to bring him into the light, but meeting him halfway, in the shadows, where their love begins to grow.
