When Abigail Pike goes hiking with her sister, she never expected she'd walk right into a seven-foot-tall green alien.

Jaril came to Earth to study its plants. He didn't intend to rescue a human when she falls and hits her head on a rock after she runs into him. To save her, Jaril must implant his technology in her.

Overcoming her fear, Abigail returns to the cave where she first met the alien. This time he's the one who's injured. The longer she's around Jaril, the more she's drawn to him, but Jaril needs to return to his ship to be healed properly.

Abigail doesn't want to give up her life on Earth, but she might not have a choice if she wants to be with Jaril. Whoever said understanding plants was easier than humans has never met a green alien vampire.
