1: A Fresh Start by rlfj This is a great take on the "going back" genre. The characters come alive, and you can really feel for their situations. This is a wonderful story to read.
2: World War: Campaign for Eastland by Lazlo Zalezac I wish that I could vote more than once. This story is the best that I have ever read, paid for or on SOL.
Please read the whole off the Jade Warrior series.
