it's been driving me mad that i can't remember either of them. the first i read quite a number of years ago, all i remember is the main character is a male (no name-sorry) and he can see these people/demons that others can't. he can also see peoples 'colours' (auras) and if he points his finger at the demons he can shot then as if his finger was a gun. i think he can also fly/go to where they come from.sorry its such a small amount of info on that one.
next book is alot less scary, it's about a women who runs a gym. shes always working out and gets really ill at the end because shes so extreame in her workouts. theres also an older lady who's seeing one of the male bodybuilders/personal trainers and one day while having sex she looks at him but he's looking at himself in the mirror while having sex with her.
any help would be great as i'm not getting anywhere searching by myself.
