Three-point-Five Stars, Rounded up to FourARC received from Netgalley. This review is not biased in any way. There was no money, gifts, discounts, or favors exchanged for this review.Hey look! There's an YA book where the love story doesn't completely take over the entire plot!I found Heartbeat on Netgalley, and since it's by one of my favorite publishers, I decided to request it. When I got accepted, I started reading it immediately.Emma's mother is brain dead, but pregnant. In fact, she should be dead, but is being kept alive by machines. Her step-father believes that Emma's brother should be born, but Emma believes that he shouldn't.Emma meets a boy named Caleb, who used to be a drug user and car thief. There's a slow development of romance between them, but is rushed towards the end.I didn't like the fact how Emma kept trying to get into fights with her step-father throughout most of the book. It seems like she didn't understand that he was going through grief, too.Heartbeat is a very short book, and it only takes around an hour to read, but it is filled with controversial issues.I'd recommend this for fans of Jodi Picoult and those who want a short and sweet novel.
