OK, women characters are rare in his work, but look at Harey (engl. Rhea) - she 's the most human in Solaris, and the only side willing and capable of making the Contact. That's one of main layers in that novel. (Although we could argue 1. is she a human or "ocean", 2. how she's actually only simulation of original Harey intermediated through Kevin's memory / perception of her / subconsciousness. - But even if that's true, she becomes new, independent person, female person, and she's doing the step which nor Kevin nor Snaut are capable of doing. Kevin's final statement of staying there in "time of cruel miracles" is only late understanding of what she was trying to do or say.)
