"Shadow of the Fox has just become one of my all time favorite fantasy novels! I'm in love with this book, its characters, its worldbuilding! Oni, giant centipedes, flesh eating ghosts, and terrifying half women/half spider things that will give me nightmares for weeks to come, this book is filled with terrifying Asian mythological creatures that make Medusa look like a mean grandma with a bad wig. Not to mention a lovable kitsune, a sexy demonslayer, and quite a few side characters that are larger than life and have completely wormed their way into my heart. I'm so invested in their lives and their quest and I cannot wait for the next installment of my new favorite series. In the meantime, I plan to re-read Shadow of the Fox again and again until I can be reunited with Yumeko and Tatsumi soon. So dear Julie, please write faster!"
