The Rescue by Lola Gabriel

He’s a dragon with extraordinary powers. She’s used to a pampered life. Can they face the world’s most dangerous evils from the beginning of time?
Amelia thought the worst of her problems came when her father died, leaving her with no real idea of who she was, why she had her powers, or what killed him. After spending years trying to figure out why he was always so secretive, she begins to forget and move on.
Meanwhile, Aegir, a dragon who can control the weather, and the last of the Guardians, finds the Pit has failed and some of the most notorious evils from the beginning of time have escaped and plan to resurrect the legendary World Serpent.
Alone, with no backup, he must stop them. An impossible battle that he takes on, knowing he will likely not survive.
However, when he rescues Amelia from imminent death, they clash immediately. Amelia wonders if he, too, is trying to kill her, but is there more to his terrifying past?
