I just did not like it. The main character fell flat for me, and when

everyone treated her like shit it got old really quickly.

I do not see the girlboss from the reviews. Her development is non-existent and I guess the best part about this book is Greek mythology, so only pick this book up if you already know and enjoy it. 
Glad I have confirmed that I do not need to waste my time on the song of achilles.
