I've read enough incest books (that sounds weird; just go with it) to know all about the squeamish feelings. Flowers in the Attic. Middlesex. And though you know a brother/sister ship is awful and gross, there's a little part of you that roots them on. 
 ...I didn't get that here. 
 Lochan and Maya are raising their younger siblings. Dad ran away with his new wife, and mom is too busy acting like a teenager herself to be any sort of authority figure. She doesn't even come home most days, spending nights at her boyfriend's. On top of raising kids and running a household, Lochan and Maya are still high school students and are also hiding the fact there's no parent at home, so social services won't come in and grab them. 
 I felt absolutely nothing toward these characters. They had no depth, no personality beyond what we're told. And that's the problem--we're told who they are. Lochan has social anxiety. Maya is pretty. Kit (their 13-year-old brother) is rebellious. There was nothing that made me connect with any of them, which made the story difficult to grasp. 
 Also, not much happens. There's a lot of filler. Maya's best friend has the hots for Lochan, which is barely mentioned once the sibling relationship begins. Lochan's English teacher wants to help him overcome his anxiety, but she had no part in the plot. She had potential, too; she could have been cool. 
 The entire story is their "romance." Nothing else happens. And their romance isn't interesting enough--or believable--to warrant caring about it.
