Dahlia had her whole life ahead of her. Until one night when she went to a party and woke up knowing that she was assaulted. Dahlia can't remember anything about who did this to her and has a hard time dealing with the aftermath of her attack. Nine years later, still suffering from nightmares and still in therapy, Dahlia works as a paralegal, even though it's not what she wants to do with her life. One day, Dahlia unexpectedly sees a video of her attack online. She's taken aback, and at first, wants everything to go away. But she then realizes, more than anything, she wants revenge.

As she discovers more about the plan behind her attack all those years ago, Dahlia learns more about the events of her past. The people involved are not who she expected. And when the last person involved is revealed, Dahlia will have to come to terms with both her past and her present...

All I can say about WHAT HAPPENED THAT NIGHT is wow. Sandra Block had me hooked from the first page, I couldn't put it down. I truly enjoyed how she had Dahlia come up with her plans of revenge. I would never have thought of any of this. I also liked how the story was told, back and forth from the night it happened up to the present. Block really had me going with this story. The ending is nothing that I expected. I guess you really don't know people sometimes. WHAT HAPPENED THAT NIGHT has revenge and some romance. If you are looking for a great, thrilling book, pick this one up, you will not be disappointed.
