I'm wavering between four and five stars. I really enjoyed the storyline and the relationships that both pairs of siblings have. I'm also happy to read anything, let alone YA, that trusts adults with disabilities to have feelings and be lonely. This aspect of living with a disability is pretty under discussed. I hope the author (who has an son with autism) writes more books- potentially adult books- that have characters on the spectrum.

I'd deduct half a star if GoodReads had the option based on the rushed ending... like many YA novels nowadays, this book could've lost the last 100 or so pages and still been a great book. I would've loved this story even without

the Ethan runaway drama and subsequent placement in an adult home

. I also wish, selfishly, that Chloe expressed more of her feelings to her boyfriend (I honestly don't even remember his name, so forgettable) and Sarah regarding the way they talked about and treated Ivy ("like pandas in a zoo"). I wanted to FUCKIN' SLAP the boyfriend when he talked about Ivy, but that was probably the point. And honestly, Chloe's thoughts and actions as written are probably much more realistic to being a teenager. So, I think it's important for adults reviewing YA to remember what it's like being a teenager and stop expecting unrealistic teenage superheroes instead of something that young people can relate to.
