Ambrosia (goes by Amb) has been invited to her college reunion and her husband has agreed they will go. The problem is, he doesn't know anything about what happened her freshman year, or that the invitation came with a handwritten note that says "We need to talk about what we did that night." Amb reluctantly goes and strange things start happening, as though someone knows the secret she and her friend Sully are keeping and is out to expose them. This thriller is told both in the present and chunks of time from back then, when it happened. I really enjoyed this story--it was definitely one of the most surprising endings I've read in a while. Not a huge or unbelievable twist, but still didn't end where I thought it would, that's for sure.
