As soon as I heard about this book, I knew it was perfect for me, and I was so right! ALL THE FEELS totally gave me "all the feels" (seriously, it has the most fitting title EVER!)! I loved absolutely every single second, and even though the Starveil fandom isn't real, I still felt like I was part of it, and I loved that! 
 If you're a big fan or fangirl over anything, I think you'll relate to ALL THE FEELS. You might not be able to relate to how involved Liv is in the fandom, but if you're a big fan of everything, you'll definitely understand how much Starveil means to her. It made me think back to how obsessed I was with a few of my favourite fandoms, and luckily my favourites have always seemed to survive, but I could totally relate to how passionate Liv felt about Spartan dying, and I loved that she did something about it! 
 Now onto Liv herself! I absolutely LOVED her! I could relate to her late night fandom binges, and her reluctance to let the fandom go. I also loved her friendship with Xander, and I thought that Xander himself was fantastic! He was such a wonderful and unique character, and I loved how supportive he was to Liv. I loved their friendship, but I really, really loved seeing how their friendship progressed throughout the story, and I shipped them so, so so much! 
 Overall, I thought that ALL THE FEELS was fantastic! It was fun, hilarious, and as a self-professed fangirl, it was extremely easy for me to relate to! Just thinking about this book has me grinning like a fool, and if you like romantic comedies with some fandom nerdiness thrown in then I think this is the perfect book for you, too!
