Just so nobody thinks I'm accusing anyone of copying someone else's work, this story ("Ricochet") and HG's story ("Forward") use similar premises, but that's all they use. The setups are different, the characterizations are different, the conflicts they work to resolve are different, and the resolutions are different. This is a case where two talented authors got the same idea at about the same time and then developed that idea in two completely different ways.
And both stories are excellent. Both of you need to keep them going! In fact, as I write this, I'm waiting for the last chapter of each story with worms on my tongue.
