I DNF'd this book at page 205 of 304, or the end of chapter 8. Normally, if I get this far this quickly (it's taken me less than 20 hours), I will push through to the end, but I can't with this one. I think there are some topics so taboo that only the most experienced, talented novelists are able to write about them well and organically. (Read: Hassinger, at this point in her career, was not one of these novelists. Hang on 'til (or skip to) the end for a book recommendation that will give you a world like Nina: Adolescence, but much better.)
Hassinger is unable to organically write in Nina, a 15 year old, willingly visiting with a man of 36, whom she knows only as the father of her younger, DEAD brother, who was conceived in adultery unbeknownst to Nina's father. She is unable to organically write in this 15 year old allowing herself to be kissed by this man, then, knowing she doesn't like it, willingly takes off her clothes at his house and is then raped (statutorily, but even then it's muddy and seems more like straight-up rape than anything) on a completely separate occasion. Had this been an organically-written situation, Nina would have been disgusted with him, just as she had been before, just as she had been with her mother for cheating on her father with this pedophile.
Hassinger makes a point to note all of Leo's flaws through Nina's eyes, and to explain the burning anger she feels toward her mother, and the sadness and love she feels for her father. Nina feels guilty that her younger brother died on her watch, and furious that the boy had been abandoned by his biological father, Leo. Which all make sense.
But what doesn't make sense is her sexuality, which should be "budding" at 15, but is instead bursting, out of nowhere. Nina goes from not being able to imagine a boy speaking to her, let alone touching her, to having sex with the man who ran away from his responsibilities - his child, by her own mother. The Nina I expected would have recoiled, not gone back for more. There isn't even a sexual progression, the "first, second, third base" thing, if you will. Leo kisses her once, and then, BOOM, sex the next time they meet up. The mild homosexuality between Nina and her friend Raissa is acceptable. Normal, even. Organic. But I was once 15, and could never have done what Nina did with Leo. I don't know if anyone but this fictional girl could have.
I became so disinterested with and unattached to Nina and the rest of her story that I didn't care what happened to her, or her mother, or Leo, or even her father, who is the only truly likable character in this book. That is why I DNF'd it - I realized that there was no possible ending I could have imagined that would have made this book worth reading from cover to cover.
To reiterate, in closing: there are some things that you just aren't able to make realistic within a novel. Some themes are just too taboo to write well, and the only way to make them work is if you're a damn good, experienced writer. As this was Hassinger's debut novel, it is clear she wasn't ready to take on such heavy topics at the time.
If you want a good book that is similar in content but written meticulously, read Lolita by Vladimir Nabokov. It certainly feels like this novel is a rip-off of Lolita. But Nina is hardly likable, with a watered-down personality in comparison to fiery Lolita. Don't waste your time with this book - you wouldn't buy generic-brand sandwich cookies if Oreos were sitting right next to them, for the same price.
