FIdGits, Book 1: Adolessons: Growing up in the Seventies

In a Midwestern town a man goes missing. All that's left behind are disks with chapters from a memoir, but the early files are protected by a password. His wife is frantic. With the loss of his income, the family faces financial ruin. She enlists the help of local publishers, who employ the services of a security expert and crack the password. Now the whole intriguing story of a young man coming of age in the raucous Seventies and Eighties can be read by someone other than the author.
Page after page, there is no explanation of the title, seven letters misspelled? The two letters capitalized? Nothing. The language is raw, the actions are brutally honest, with graphic sexual content that is so complete it should be embarrassing. Despite its exceedingly graphic nature, the editors decide to publish.
Something is missing though. There is a prologue, an introduction, but no epilogue, no climax. Just prior to publication, a judge rules the missing man legally deceased, and the family can now collect the life insurance. The rush to publish in order to help the family now seems unnecessary, until the manila envelope with the memoir's climax arrives in the mail. Is it from the missing man? But he's supposed to be dead. Who sent the mysterious envelope and why?
