I received an arc from the publisher via netgalley in exchange for an honest review 
 I don't know how to express myself in this review other than typing 'I loved it' until I run out of room. 
 There's a lot of themes explored in How to Make a Wish. The first one is obviously Grace's relationship with another girl, subsequently falling in love with her. It's a very believable romance whilst also being a very sweet romance. It's a romance between a bisexual girl and a biracial lesbian and is one of the best parts of the book. They had amazing chemistry and is now one of my personal favourite f/f relationships. I also loved how the book let them have sex and wasn't at all ambiguous about it. I feel like this is a result of YA finally allowing their characters to have sex, and as sex between girls is practically non existent, the sex scene in this book was a welcomed surprise. 
 The biggest theme of this book was definitely Grace's relationship with her mother. Grace's mother, Maggie, is neglectful and dismissive, and the book makes it clear that this affected Grace. From her mother never lasting in a relationship, to dismissing how she may negatively be affecting Grace. Grace never unrealistically forgives her, nor is her mother ever excused. There's also no cop outs from Grace feeling at the end of the book that despite all that, she needs to love her mother and stick by her. The book makes it clear some parents are shitty and you shouldn't have to put up with them. I loved how something as small as nail polish plays a role in Grace's relationship with her mother, how that was something used to portray their connection. 
 I really liked the side characters too. I adored the love interest, Eva. She was a very likeable and compelling character. I loved Grace's best friend Luca. I love how he was supportive of her sexuality from the beginning, and I also loved how there was no subplot of him having a crush on her or anything of the sort, it let a guy and a girl be friends without anything else. 
 I highly recommend picking the book up when it's released. Definitely a new favourite.
