Forgetful scientist Simon Morgan lost his chance with Amity Archer ten years ago. He knows there is no hope...until a sea captain trades a meal for an ancient stone reputed to have the power to give him his heart's desire. Immediately after pocketing the stone, Simon runs into Amity. Did the ancient artifact cause this chance encounter or was it mere coincidence?

Like her favorite travel writer Mrs. Peabody, Amity Archer yearns for adventure, but she's horrified when her father asks Simon Morgan to escort her on her first real adventure.

With Amity's Aunt Clementine as a buffer between them, will Simon be able to prove that his love for Amity is real? Can Amity show Simon that her love for him has nothing to do with a so-called magical rock?
