Protected by the gods and powering the three Great Portals of Kindness, Art, and Language, The Web of Time re-arranges itself as humans change their minds, fall in love, or cause empires to rise and fall. When the Great Portals close from the world, time begins erasing itself, histories start to disappear, Earth falls into chaos, and the gods don't know how to stop it-until Jack meets Anna.

Anna is a passionate and solitary writer who is protected by her companion, Nafusa of Libya, the cat god. When Jack, a young painter harboring a traumatic past, falls through the Great Portal of Art in Tunis, he stumbles into Anna, and his fate.

Helped and hindered by a rotating cast of deities, the two embark on a journey that connects three ancient cities in different times: Rome, Tunis, and Tripoli. They realize that it is Anna's gift for healing words and Jack's natural talent for drawing places as they were that can reinstate the Great Portals and restore the world's balance, but some of the darker gods who thrive on chaos will stop at nothing to derail their quest. As time tears faster than they can heal it, Anna and Jack must come together in time to save history, and the possibility of a future.
