The Perpetual Series — Janna Hill

Perpetual Darkness is told from the man's perspective; this is his side of the story. Max Hubbard is a drifter and like most transients he prefers living a life of anonymity. That is until he lays eyes on Abigail. “He merely followed his instinct, not giving any thought as to why he watched her.”
Perpetual Spring is told from the woman's point of view; this is her side of the story. After being forced into early retirement Abigail leaves Missouri and settles in the quiet countryside of La Grange. It's in this sleepy landscape she finds herself strangely attracted to the man who is watching her. “Some might consider him a stalker but she preferred to think of him as a guardian of sorts.”
Is this another Romeo and Juliet? No, but a tragic romance nonetheless.
