Trifecta is part of the Jake Thread #2 world but is sort of a stand alone. We are of two minds here because much background from Jake T2 is not recapitulated in Trifecta. Still it may be possible to read it without Jake T2 under your belt... It would be a very different story for the reader in that case. I'm not ready to recommend that.
Thanks again to Grisbuff for the masterful edit.
I hope you enjoy it.
