Sixteen-year-old Samantha Stewart must overcome her fear of the family legacy, or curse, as she sometimes calls it. But as the next Guardian of the Artifacts, she has a lot to learn before that can happen. When her best friend Nicole receives a mysterious letter from 1929, London, Nicole begs Sam for help. Sam hesitates out of fear, but once she decides to help, Nicole has already transported, but where? London? Sam’s anxiety of all things artifacts stops her cold, especially the Roman bricks that create the portal for time-travel, but when she returns to Aunt Eli’s vault in the Throne Room and finds the bricks glowing, she must act. Did Nicole open a portal and use it without her? But how, and did this have something to do with the letter she received from London? A whiff of lavender used in all time-travel spells confirms her fear and, in a panic, she runs to Archie, the magical cat and Protector of the artifacts. Only he can help her prepare a time-travel portal to save Nicole and unravel this mystery, but can she trust him? And will she arrive in time to save Nicole?
