The Guardian by A.M. Mahler

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 Eleanor from highway bandits and discovered she was the Guardian of a Philosopher’s Stone. Now, the quest is on to keep the stone from sinister hands. In the first installment of a four-book series, 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.

With the gift of eternal life, Nora has been searching for a hundred years for the Scholar, the Healer, and the Fox, so that together, they may use the stone for good and keep it away from evil intent. Nora is convinced that Jack is her Warrior and will protect her in her journey at all costs. All she has to do is teach him it’s all right to love, to trust someone else, and depend on them to help you achieve your goal. She’s determined not to fail, but she’s hiding a secret that threatens to tear their newfound love apart.
