A Strange Fire (Florence Vaine #1) by L.H. Cosway
When her dad decides to ship her off to live with her grandma in the sleepy town of Chesterport, Flo thinks that this is her chance for a better life. But on her very first day at her new school she is ridiculed and laughed at for having a stammer. One student sticks up for her and his name is Frank.
Frank’s body is surrounded by an aura of fire, but Flo is the only one who can see it. He lives in a foster home for troubled teenagers. Flo is drawn to him because he’s different and so is she.
Things are about to get scary, because Chesterport is not your ordinary suburban town. It’s infested by a coven of dark witches who prey on the young and the elderly. Soon Flo discovers that she’s next on their list of victims, and finds herself fighting a battle she never would have imagined possible.
After spending seventeen years as an Empath, thinking she was either delusional or very, very different, she has found others who are different too. She helped battle a coven of dark witches and watched as their leader got sent to her judgement. All now seems peaceful in her new town, but it's not going to last.
For one, Flo's dad is back on the scene and has taken over her dead grandmother's house with his new girlfriend. Dealing with him makes Flo think that maybe everyday people can be monsters too, as he blackmails her into giving up the one person she needs the most. Secondly, Flo hears a story about strange goings on in the nearby forest, and becomes obsessed with the magical things that might lie in its green depths.
A Vision of Green is the second instalment in the Florence Vaine trilogy, where Flo finds herself yet again immersed in mystery, romance and things that are just a little bit scary. She will come across new adversaries, supernatural and otherwise, discover more about her own identity and grow in ways she had never anticipated.
