In this story, one of the main character, I believe the name is Sheen, travels through portals between worlds, in one of them she meets a unicorn. It is part fantasy, part sci-fi. The character discovers during her journey that she is a robot (a machine, hence her name). I recall a cover with the face of the character, with blue color. The book must have been from before 2010, I would guess between 1980 and 2000.

Piers Anthony's Apprentice Adept series, probably Split Infinity:

The Game-champion serf Stile is assaulted on Proton by an unknown enemy, but learns he can escape into a mysterious fantasy world (Phaze). In Phaze he meets Neysa, a unicorn, and learns of his magical legacy as the Blue Adept. Back in Proton he tries to uncover his enemy, while building a relationship with his robot lover, Sheen.

    Great, Thank you ! I have been looking for it for a long time. As I had read it in french, I couldn't find the right places to search. The name in french is "l'Adepte Bleu" serie, book title : "L'infini éclaté", in case some further french readers search for this.
