It's not all that often that I read a novel where I am completely swept up in the story but also admire the writing; luckily, The Last One is one of those novels and I enjoyed the hell out of it. From the reviews so far, I think people will either love and think clever Oliva's use of third person omniscient present/future narration (basically, "real life" while making the reality show is narrated as if by a writer-producer creating a reality show narrative, and I loved it) and the first person narration is well-done too, even though I don't enjoy first person nearly as much as third. I also enjoyed the use of the reality show monikers as the characters "real names." I would not say that I am a fan of reality shows but I was living in college dorms when they were at their height and I remember watching them in huge groups of fans, all of whom had these sorts of nicknames and monikers for the contestants. I loved Oliva's moxy in not concretely linking real names to the reality show moniker -- and I have a feeling she fought editors on that one. I also enjoyed the Reddit threads that looked and sounded just like Reddit but without calling it such. 
 So why not five stars when I like it so much? (view spoiler)[A few minor things: I was sick of the delusions about three chapters before Zoo came to her senses and I hated the focus on Miles once she had. I don't know why I hated it, because typically that's the romantic touch that I enjoy in a non-romance-genre novel. Maybe because Miles ended up alive and looking for her too? Add all of this to the ridiculous way Zoo acted with Brennan when he tried to talk to her about her house and husband and it all felt too forced-too forced for five stars (hide spoiler)]. 
 All of my issues are purely subjective so it's worth the read if this is remotely your kind of tale.
