Okay huge disclaimer here: I read an advanced reader's copy of I Am Princess X and it did not have any of the illustrations in it (which was pointless, but what can you do?). So, I'm judging this book solely on May's storyline and not on Princess X's storyline since little snippets aren't enough to get a feel for that whole plot point.
Disclaimer number 2: This book is NOTHING like Sarah Dessen's novels...not even if you turn your head and squint. So, if that's the main reason you're picking up I Am Princess X (like it was for me), then you might want to steer clear of this book.
Now, I don't give 1 star ratings lightly. In fact, I always feel incredibly guilty about giving out 1 star ratings that I tend to just up it to two stars. However, I just couldn't find anything to like about I Am Princess X. I found it all to be a big, jumbled mess. But most of all, I found it to be way too inconsistent to find it in any way enjoyable...or rather May was incredibly inconsistent. One thing (and granted, this one is a minor thing), that bothered me was that she's a teenager...and with that mentality, she should be somewhat tech-savvy. Or at least savvy enough to know that if your frigging computer won't turn on and you think your battery is fried, how 'bout you leave it on the charger and see if it, oh I don't know, actually CHARGES? Common sense! I get that the whole point of that was so that May could meet Trick and get the whole Princess X investigation going, but really? She couldn't have gotten an actual computer virus or something more difficult to solve than "My computer won't turn on because I'm an idiot who hasn't charged it?" And another thing: Princess X is supposed to be this whole huge phenomenon that's all over the internet and you're telling me that May, who mentions she has numerous social media accounts, has no clue that something this huge exists? Uh, no. I call BS. Again, May wasn't the brightest bulb. Because the one thing you should worry about when you're trying to find your BFF and numerous people are being threatened and being hurt is what your hair looks like when you accidentally get on TV. May, you're shallow...sit down. And the amount of times the word "dude" was used in this book aggravated me...I think I now hate that word more than I hate "bae" (and I LOATHE bae). Oh, and you can also find news reports of crimes that have happened YEARS ago without having to resort to printing out newspapers in the library. So May's dad, you sit down, too.
I also wasn't enamored by the writing in I Am Princess X. It seemed stilted and forced. I found myself thinking that maybe I would have liked it better had it been told in the first person narrative (especially since May's supposed to be this great writer) or maybe it would've actually made me dislike May (instead of just thinking of her as ridiculous). Princess X (I no longer feel like writing the full title) was also a whole bunch of telling. This wasn't a story that peaked my imagination and made me actually see the events happening in my mind. I don't like flowery, purple prose, but a little descriptive writing doesn't hurt anybody and can be good for the soul. But there were no descriptions here. I was also told every little mind-numbingly boring thing May and Trick did. May walked to get a Coke out of a can...Trick and May walked to get coffee because May likes coffee with chocolate in it because it doesn't taste like coffee...is that coffee going to sprout a human with a katana sword and stab somebody? No? Then, okay, it's not important, so get back to the actual plot. May also didn't pick up one of her father's calls because she knew her voice would sound like mud when she did...what exactly does mud sound like? Really, I want to know. Princess X also had paper-thin development...plot-wise, character-wise, everything-wise.
I'm just going to stop here to avoid giving away any spoilers. I will say that I didn't like I Am Princess X. The mystery behind the whole thing could have been slightly interesting, but it wasn't. I didn't like the writing (but the author's written over a dozen novels so clearly other people do) or the resolution of the plot...or the plot itself (despite the fact that it sounded interesting). I say, skip it. (Or maybe check it out and tell me if the illustrations make the story better).
