Classic Thriller, Brilliant in Its Twists, WHAT HAPPENED THAT NIGHT by Sandra Block

Take all the horror stories you've read in the "real news" about sexual molesting at frat houses and other university clubs. Add to it the humiliation and shock of a gang-rape victim who can't remember what happened, thanks to being drugged -- but who arrives at a hospital wounded and damaged in every part of her body, and who eventually finds her office mates watching a video of her assault.

That's the baseline of WHAT HAPPENED NEXT, one of the best classic thrillers I've read this year. But author Sandra Block goes way beyond the suspense and desperate desire for crime solving that this situation inspires when she provides for Dahlia, barely functioning as a paralegal, to find the support she needs from a shy "IT" guy (programmer) named James -- whose "differentness" is captured in the term "Asperger's syndrome." Except for the highly pertinent fact that the term misses out on both his persistence and his tender ability to care for Dahlia. Which is, of course, an astounding situation for both of them, but especially for Dahlia, whose effort to kill herself some time ago made complete sense.

The video's arrival online marks the moment Dahlia chooses to move from ultimate victim to a force for justice. Not necessarily legal justice -- but a fierce and furious balancing of the scales against at least four of the men who raped her and made fun of her painful abasement.

No wonder James seems like an amazing answer to her needs: On his body, unlike the tattoos on Dahlia's, is a string of Japanese characters spelling the word for "revenge."

I could not put this book down. The twists, the suspense, the emotional connections building against the odds between Dahlia and James -- it stunned me. There are also interludes of flashback to the year of the rape, like this one in Dahlia's voice:

It is a bit shocking, but I love my tattoo.

It's the one thing I've managed to accomplish over the last couple of months in Cambridge. Ink. It was like therapy. My tattoo artist, Claire, asked why I wanted a tattoo. I told her that I wanted to take my body back. And she said "Cool" quite simply, and that was that.

We talked. Well, I talked, and she listened. It hurt, sure, but I really didn't mind. It was my idea. My pain. And while she etched survivor on my arm and surrounded it with darkness turning into lightness, I felt better. Tattoo therapy, maybe. It was better than that Rae-Ann woman anyway, who just drank tea the whole time.

I don't try to explain any of this to my mom.

What intrigues me most about WHAT HAPPENED THAT NIGHT is the way it shatters the genre conventions so successfully. Face it, a gang-rape victim turning to revenge -- that should be darkness all the way. But Block commands a rising and wakening from her plot and characters, and the ending is almost too tender to bear -- but not really. It fits, as inevitable as it is surprising.

Don't let the brutal crime involved keep you away from grabbing a copy of this book (new from Sourcebooks Landmark). It's a compelling read, a memorable one, and, dare I say, a lifesaver. Or so I mean light-saver? Yeah, like that. (By the way, it's blurbed by Lisa Scottoline, and deserves it.)
