I have had several ask, so I thought I would try to cover on this a bit in here.
No, there is no "missing chapter" at this time where Pete and Mandy get married. I purposefully ended the first series when Pete and Mandy got engaged, as I felt that was the appropriate ending point for his story.
It must be remembered, his story starts in 1981, and ends in 1994. And the next main story centering around George starts in 2003. That is almost a decade of things that happened, much of which I touched upon in over a dozen short stories I wrote that are set in between the two.
As for the ones centered primarily on Pete and Mandy, those would be "No Regrets", which quite literally is set right before the two of them fly Rosy and Linda up for the wedding. And "Maiden Deception", which features a pregnant Mandy about a year after they got married. But many are also lead-ins for the "Country Boy in the City" story.
Like expanding "Honey Silver" and her friends into more than the one-off character she was in Linda's story. Or how Linda in less than a decade had a kid, a nice house, as well as a cache of guns and cash in her house.
And giving the readers a lot more information, so they would know (even if Pete was largely oblivious) that Pavel was not such a nice guy. He is actually loosely based on somebody I actually knew. Who was a Ukrainian Jew, operated several legitimate businesses in the LA area, and was a member of the Russian Maffia.
Pete is largely a "Candide" character. That was a story written by Voltaire about a man that simply lived his life with an optimistic outlook on life, and was largely oblivious to much of what was going on around him. In many ways "Forrest Gump" is similar, and the porn movies "Pretty Peaches" and the "Candy" series are also based on Candide.
George, is much less of a Candide. He is cynical, more than a bit self-absorbed, and willing to use others to get what he wants. In many ways, he is an "Anti-Pete". But also realizes as the story progresses that actions have consequences, and in many ways is forced to sit in his own shit because of his bad decisions. And that not everything he believed at the start is reality, much is purely a construct he and others around him have made.
However, for those that are curious I am drafting out how to write a story about the wedding itself. And it will likely be an interesting wedding. As Linda and Becky are both there, and both are still terrified of each other. But I think it might be fun, as it will allow me to use a POV character I have not used so far in the series.
