Good beginning and middle. Lousy end.

Six Years - Harlan Coben

A college professor, Jake Fischer, has a summer fling with Natalie. He falls head-over-heels in love only to have her marry Todd Sanderson at the end of the summer. Natalie asks Jake to promise he won't bother them or try to contact her, but six years later he runs across an obituary for Todd. Wanting to see Natalie, he attends the funeral but discovers that Todd was married to someone else and had a different family. Natalie is nowhere to be found.

**Possible Spoilers** I don't want this to sound like I didn't like the book, but as the conspiracies surrounding Natalie's disappearance and the link to her father's vanishing many years earlier, not to mention the increasingly large (huge) number of people who seemed to be in on the secret, we merged into merge into fantasy land. And the idea that Minor's son, who wanted to go straight, and who wanted to retrieve the papers proving he had plagiarized because they proved he was as bad as his father, would kill the professor over the papers? Proving he's a good guy? WTF? 

Not to mention that Jake had promised Natalie at the wedding he would not ever try to find her. And he receives a message during his search asking him to hold to that promise. He should have: a promise is a promise. Would have saved everyone a lot of trouble. 

Fun read, though.
