Finding Gaia is a 2012 novel by Kimberly Chapman. It's hard to put it in a single genre, but it contains definite elements of Romance and Fantasy, with some topics reminiscent of Sci-Fi.
The story starts centered on Jason, a centuries-old immortal searching for another immortal who he has discovered through her (occasionally catastrophic) interactions with society. He's helped by his closest friend, Trish, for whom he acts as somewhat of a surrogate father, and Don, Trish's husband. He eventually finds her and the main story arc begins. The book explores what it's like to live on past your own time, and has some fun with the rules for how the main character's abilities work.
Finding Gaia contains examples of:
- Complete Immortality: Jason and Anna. Played straight and subverted at the end of the book.
- Elemental Absorption: Anna does this to recoup her powers after overexerting herself.
- Life Drain: This turns out to be Jason's superpower.
- What Kind of Lame Power Is Heart, Anyway?: Averted. Female Green Thumbs are generally the least powerful of any superhero group, but Anna is legitimately more powerful than Jason, a fact which everyone involved is aware of.
- Who Wants to Live Forever?: Jason and Anna's situation is occasionally portrayed this way.
