“Tricia Sullivan writes novels that are so entertaining they’re almost embarrassing. Seriously, when was the last time you read a really smart book that was also fun?” - Patrick Ness

“A genuinely kick-ass protagonist with personality.” - Lauren Beukes

“If someone doesn’t turn Shadowboxer into a kickass martial arts film there’s no justice.” - Jon Courtenay Grimwood

“Hits like a punch to the gut.”- Marie Brennan

“Shadowboxer is a fast-paced, gripping contemporary dark fantasy thriller. Everything about this book feels utterly real from the monsters out of Thai mythology to the cage fights, but especially the incandescent Jade Barrera whose passion and fury are sometimes bigger than she can control.” - Justine Larbalestier

“In this adrenaline-fueled supernatural adventure… Sullivan brings to life the beauty of Thailand and the sweat and blood of the gym, infusing them with magic and danger.” – Publishers Weekly

“Mixed martial arts, Thai legend and human trafficking come together in this gritty fantasy adventure… Jade's strength and tenacity make her an appealing protagonist—and it's refreshing to see a black Latina lead, given their rarity in fiction for teens.” – Kirkus Reviews
