*I received a copy of THINGS I SHOULD HAVE KNOWN from NetGalley in exchange for an honest review. 
 THINGS I SHOULD HAVE KNOWN is a heartwarming book that deals with heavy topics in a beautiful way. Autistic kids are represented very well (and another thing, which is technically a spoiler), and I appreciate that so much. 
 c h a r a c t e r s: 
 Chloe. Obviously, she's a pretty big part of the story, being the main character and all. I liked her, but I didn't love her; I did feel like I would have made the same decisions if I was in her spot, though. (view spoiler)[It was SO great when she broke up with James, though; as SOON as he said something off about Ivy, I was ready to throw him out the window. Same with Sarah, even though they're still friends. (hide spoiler)]She handled everything gracefully and always defended Ivy, which is obviously wonderful. 
 Ivy. She's probably one of my favorites; so sweet, too good for this world, too pure. She only wants what's best and ahhh she's just SO nice. (view spoiler)[I did love that she was gay! I don't think I've ever read a book with autistic characters before, much less a gay autistic character. (hide spoiler)]I feel like she represents everyone on the autistic spectrum well- which we can attribute to the author- but... yeah. She was just wonderful. 
 David. Okay, we didn't get too much of a description of him (or we did and I forgot about it), so I kind of pictured him like Clark from THE UNEXPECTED EVERYTHING. (I definitely can't complain about that.) I appreciated that he had a reason for being so ~cut off~ from everyone- and his sassy remarks were EVERYTHING. (view spoiler)[His and Chloe's relationship were so great, too; they didn't rush it and that is p e r f e c t l y fine with me. (hide spoiler)] 
 Ethan. Ethan is so sweet. SO SWEET. He deserves everything good in the world, multiplied by two. I honestly can't express how wonderful he is. I liked his development- if you can call it that- and, gahhhh, he's just so cute and adorable. 
 James and Sarah. I'm not lying when I say that I want to fling them out the window. Yes, James is legitimately a Clark Kent lookalike, which I always appreciate, but he's so self-centered; same with Sarah. I can't believe how inconsiderate and rude they were, too. They just annoy me to no end. 
 p l o t & w r i t i n g: 
 The plot was simple at first and then expanded into something I appreciate so much that allowed for more development and wonderful-ness. While the writing was okay but nothing special, it was just perfect to grow and expand the plot; I was expecting a simple love story between two autistic kids and a side story about those kids' siblings falling in love somehow, but nope. THINGS I SHOULD HAVE KNOWN was not that, and I'm 100% fine with it. The characters were probably my favorite part, but this book also had a good consistent plot with equally good writing. 
 o t h e r: 
 I did like how the relationship between Chloe and her stepfather, Ron, became fairly less strained. That was a nice touch, even though I still kinda hate him. 
 The cover is beautiful, okay? It's so pretty. I love it. 
 The relationships in THINGS I SHOULD HAVE KNOWN are well developed and written, with nothing going too slow or too fast; I just appreciate that so much. 
 All in all, THINGS I SHOULD HAVE KNOWN is a wonderful book with representation of autistic kids (view spoiler)[and gay autistic kids, which is even better, (hide spoiler)] and it is very enjoyable. I reccommend it for anyone who's looking for a nice, fairly-well-written read.
