Let’s revisit the defining young adult novels of the past ten years that captured our collective imagination.

The Defining YA Books of the Decade

1. Six of Crows by Leigh Bardugo (2015):
This gritty fantasy heist novel introduced us to Kaz Brekker and his crew of outcasts, redefining what YA fantasy could be. Dark, diverse, and dripping with morally gray characters, it’s become a staple on every YA fan’s shelf.

2. They Both Die at the End by Adam Silvera (2017):
Silvera’s gut-wrenching story of two boys who meet on their last day alive became a TikTok sensation years after its release. The poignant exploration of mortality and connection still resonates deeply.

This groundbreaking novel about police brutality and systemic racism struck a chord worldwide, catapulting YA into conversations about activism and social justice.

4. A Court of Thorns and Roses by Sarah J. Maas (2015):
Fantasy romance got a spicy upgrade with Maas’ fae-centric series. Whether you’re here for the slow-burn romance or the brooding winged dudes, ACOTAR solidified Maas as the queen of dramatic fantasy.

West African mythology meets a rebellion-fueled fantasy in this epic, richly detailed debut. Adeyemi’s worldbuilding and themes of power and oppression struck a chord with readers everywhere.

Blending Arthurian legend with Southern Black culture, Legendborn is a masterful mix of fantasy, mystery, and identity exploration that feels both timely and timeless.

9. One of Us Is Lying by Karen M. McManus (2017):
This Breakfast Club murder mystery had readers hooked with its twisty plot and unreliable narrators. YA thrillers were never the same.
