<b><i>Things I'll Never Say</i></b> follows Casey, an eighteen year old fat, bisexual surfer, who's grieving the death of her twin brother while also juggling her feelings for both of her best friends. The story is told through a series of journal entries that Casey writes to her dead brother as a way to let out her feelings. 

The way grief was explored in this book was so beautifully heartwrenching. We get to see Casey go back and forth between anger at him for the overdose, confusion on how she's supposed to go on feeling like half a whole and most painful of all, acceptance that he'll never come back to her. Throughout all of this, Casey also struggles through a budding drug addiction and it was interesting to see how she dealt with the fear of becoming just like her brother. It all felt very palpable.

If the book had been solely focused on the grief aspect, I might have rated it 5 stars but the romance bit was underwhelming. None of the best friends felt real to me and other than the fact that they ended up in a polyamorous relationship, there was nothing else that really stuck out to me about them. 

I loved how the book ended the same way it started, with Casey and Sammy, her brother. It was very much an open ending but we got to see somewhat of a curtain being closed on Casey letting her grief control her life and how she enjoys it and I found that to be a perfect way to end the story. 

I would recommend it for anyone who enjoys stories about sibling love and loss!
