When magic can’t help the immortals in Chicago, where do they turn? Enter Madison. A human researcher with zero knowledge of immortals, and a chance meeting with lion shifter, Garrison. Both have traumatizing pasts, yet something pulls them together. An old wound reopens, but she thinks nothing of cleaning the wound that doesn’t heal on its own. Can human medicine help the immortals, or is it too late? Can humans and immortals coexist?
