"Bloodchild"

Octavia E. Butler famously called this her 'pregnant man' story, but I wasn't even thinking of gender when I was reading it. Starting with 'My last night of childhood began with a visit home', this is a coming-of-age-cum-alien-host-cum-love story. Butler's exposition is a marvel to behold - sure-footed and subtle.

• She was paler and smaller than T'Gatoi - probably born from the body of an animal. Tlic from Terran bodies were always larger as well as more numerous.
• After that he concentrated on getting his share of every egg that came into the house and on looking out for me in a way that made me all but hate him - a way that clearly said, as long as I was all right, he was safe from the Tlic.
• "I wouldn't have shot you,"I said. "Not you." She had been taken from my father's flesh when he was my age.
