Tampered Destiny

To save her mother's life, Myra comes up with a plan to travel back in time and return without any of her team knowing. Myra's excursion to the past goes according to plan until she steps through the portal to return to her lab. To her surprise and consternation, she ends up on an alien world with a hoard of dragons. The time machine has malfunctioned and either killed her, and she's gone to the afterlife, or she's been badly hurt and hallucinating.
But the exotic hunk called Odon feels far from a hallucination.
