I vaguely remember a book which I would like to read again. The plot was like this.
A man lives an ordinary life but one day he starts having some memories ... or headaches, I don't remember. The main thing is that he discovers he is able to feel and communicate with electric devices around him. And as soon as he discovers it, he starts having serious problems with some organization which had trained him and used his abilities for wrong purposes. Slowly he regains more and more memories and is forced to run and hide from physical and telepathic assassins. I remember, that there was one mystical "electrical being" which acted as his invisible "guardian angel" and this being had helped him in his early childhood when he was in a hospital. This being could manifest itself to the physical world only through electrical devices.
There was a woman who also had some telepathic abilities and her telepathic presence always was accompanied by some specific scent, like some flowers or something. This woman was an assassin sent to kill the protagonist, but then she switched sides and died. But the "electrical being" saved the woman, taking her into some "electrical" level of existence.
The style of the novel was mostly light and active adventure story. Not exactly teenager book, but also no any serious philosophical value to it.
