Recently I read the Last on Earth series by Marilyn Kaye. It was published in the 90's and consists of three books. The premise was interesting: 25 NY seniors step out of their basement class to discover the entire population of the world has disappeared. The books explore what the teens do about this, how they cope, what happened and what they can do to fix it.
The writing is so-so. It's a little juvenile, though I remember the few teen books I read in the 90's sounding similar. Maybe that's why I stopped reading age-appropriate books back then. The characers are rather stereotypical and seem to have little depth. She works some in, but it just isn't enough for the reader to give a crap about them. My first issue came at the start of the book, when the 25 seniors of this NY high school for gifted and talented kids emerge from a geomotry class. I realize my experience is limited, but wouldn't kids at a special high school be in calculus or trigonometry? That's what I took as a senior and I was by no means gifted and talented. Beyond that, the story was a bit trite and the ending was anti-climactic, though it was food for thought.
I also started to read Quentel by Deric Budendorf. I should have done my homework before paying $12 for the book. It is self-published, which had I known would have been a red flag. The reviews were scanty so it was hard to get a real grasp on whether the book was any good. The one review that was glowing, I honestly suspect the person never read the book. All they said was what a great guy he was. I further found out he wrote it in high school and pubbed it in 2007 when he was in college. He really did himself a disservice. The story is interesting: all adults have died of a mutant virus and kids must band together forming clans for protection and survival. The writing was terrible, plot development was sporadic and disorganized, characters were undeveloped and he would go from trite, juvenile prose meant for MG to topics more appropriate for YA to attempts at flowery prose one might read in a tawdry romance novel. The dialog was just awful. People, especially kids, don't talk like that. I couldn't get further than 1/4 in before I gave up. It's only the 2nd book ever that I failed to finish and I've read some bad books. The 1st failure for me was Dr. Zhivago when I was 14 and that was just because I couldn't finish (or comprehend) it before the book report was due.
