Guarding His Heart — Carolyn Spear

First grade teacher Cassidy Sinclair loves all her students, but one little quiet boy is special. His background is so secret, he even has a bodyguard, who is tall, quiet and hot. When the school is attacked, the boy's protector appears out of nowhere and dies saving her and little Allan. Solitary shifter Trevor Greene uses his innate ability to blend in to his surroundings to protect high ranking members of the Paranormal Syndicate and their families. He risks revealing his secret -- and the paranormal world -- taking down the murderous gunman threatening his six-year-old charge and his sexy teacher. While healing his physical wounds and facing the guilt over the loss of life from the attack, Trevor receives his new assignment: Cassidy Sinclair. Once she recovers from seeing him alive, he is torn between duty and passion. Cassidy requires nothing less than full disclosure. Can he overcome his distrust of humans before another attack takes her away forever?
