Janet Edwards is an English science-fiction author most well known for the portal universe series. This includes both the Scavenger Exodus and Earth Girl series as well as several novellas and short stories. She has also written the Hive Mind and End Game series.
Path to becoming a writer
Edwards read a lot of books as a child, particularly science-fiction and fantasy.
After studying Maths and working on writing technical documents for some years she decided to try writing.
Edwards started her foray into writing by taking a writing class in 2007. Two of the short stories she wrote in the following years won writing competitions while several others made the short lists.
Encouraged by those early successes she wrote two novels which she latter scrapped and did not publish. Her third novel was Earth Girl. 
Earth Girl trilogy
The Earth Girl trilogy is a science fiction series set in a distant future in which Humanity can travel between planets by portal, except for the unlucky few Handicapped whose immune systems can't handle any planet but Earth. The protagonist, Jarra, is one of those few, and she was sent to Earth at birth to save her life but was abandoned by her parents. She can’t travel to other worlds, but she can watch their vids, and she knows all the jokes they make. She’s an “ape,” a “throwback,” but this is one ape girl who won’t give in.
