The Ascender. The Bounded Curse, #2

The hunt for the key becomes a race for survival. They'd only wanted to know if the fairy tales Avery's grandpa told her were true. Now she and her friends, Cain and Bastein, have accidentally awakened an ancient terror named Romanhalth, unleashing it upon their magical realm of Esquira, spreading fear and confusion. They've already faced many dangers in their quest to find Uris Amos, keeper of a key rumored to open a passage to another world.
With the key lost and Uris nowhere to be found, the trio of heroes continue their quest, through old archeological sites and to a city where they might uncover the secret of Uris's location. But Romanhalth stalks them. He already knows about the hidden world. He only lacks the key. Every step brings the trio closer to answers, yet also closer to the monster that should never have been freed. The three friends are the only ones standing between their world and annihilation.
This is no longer a quest for truth. It's a race against a nightmare that could devour Esquira itself. Perfect for fans of YA fantasy adventure, perilous quests, and high-stakes magical journeys, The Bounded Curse series drags you into a world of myths and legends, where danger lurks at every turn, ancient evil stalks a trio of friends, and heroes are forged in fire, or destroyed in the dark.
