The Guardian - Guardians of Eternal Life, #1

A stone that grants eternal life. It's her job to keep it safe. It's his job to protect her at all costs. Jack Justice didn't believe in love or the power of the human spirit and was fresh out of faith. But that all changed when he saved Lady Nora from bandits and discovered she was the Guardian of a Philosopher's Stone. He had never met her before, but she haunted his dreams for as long as he could remember.
With the gift of eternal life, Nora has been searching for a hundred years for the Scholar, the Healer, and the Fox, so together, they may use the stone for good and keep it away from evil intent. She is convinced that Jack is her Warrior and will protect her in her journey. All she has to do is teach him it's safe to love, trust someone else, and depend on them to help you achieve your goal. Can Nora restore Jack's faith in love? Will Jack give up all he knows for a dangerous adventure? Now, the quest is on to keep the stone from sinister hands.
In the first installment of the four-book series, Guardians of Eternal Life, Jack learns the power of teamwork, the importance of family and friendship, and how far he will go to protect the woman that has come to mean everything to him.
