About 10 years ago I read a book about a woman who woke from a coma to find herself as a museum exhibit on another planet.
There were lots of other creatures in the room including a baby boy. She took the baby and escaped. She traveled with the baby for months, having various adventures and meeting lots of different life forms who helped her. It finally turned out that the baby was a stolen prince. He had a twin sister.
It was a novel in English. Unfortunately I have no memory of the cover.
