Cuckoo's Egg by C.J. Cherryh

‰ЫПI took an alien, I held it, fed it, warmed it‰ЫУit was small, but it would grow. I took it up on a mountain and lived with it alone. I slept under one roof with it, I made it angry, I encouraged it and pushed it and I had nightmares, minnow, I dreamed that it might turn on me. There were times I held it that my flesh crawled; I did these things.‰Ыќ
