Wow! As a fan of Sarah Hagger-Holt's previous book (Nothing Ever Happens Here) I knew I wanted to read Proud of Me as soon as possible. Thanks to Netgalley for allowing me to read an e-arc for review. I don't know where to start! So many positive things to say about this story and the characters within it. The story is based around a family with two mums and two kids that were conceived using a sperm donor. The plot revolves around secrets, Josh and Becky having one each and then a family 'secret' ... although the family secret isn't exactly a 'secret', more something that just isn't talked about. The book moves between Becky and Josh's points of view chapter by chapter, which works so well to show how their lives fit together, it reflects on their similarities and differences, the things they share and the things they don't. Many elements are addressed in the story, from LGBTQ+ rights, religion, friendships, coming out, relationships, being donor-conceived, internet safety, opposition, and hateful views. But, they are all done so, so well! Through the ups and downs it all comes together to leave you with a full-heart and a lovely rounded ending (my biggest peeve is a poorly finished or rushed ending). I look forward to purchasing this book for my school library and recommending it to the students, as I have with 'Nothing Ever Happens Here'. I hope Sarah Hagger-Holt continues to write more books like these for young people!
