Midnight Embers (Lumos Gems Chronicles #2) by JoAnna McSpadden:
 
In Midnight Embers, the gripping second installment of The Lumos Gems Chronicles, the aftermath of the bone dragon battle leaves our heroes reeling, their unity fractured and their world in turmoil.

Anthony, torn between his desire for adventure and the weight of responsibility, grapples with his place in the world, while Liam wrestles with haunting visions that threaten to consume him. As tensions escalate and shadows gather, a mysterious girl arrives, revealing she’s being pursued by another Lumos Gem monster—the Crimson Ravagers.

With the Water Stone stolen and a malevolent Noxenos on the rise, Anthony, Liam, and Katerina embark on a perilous quest to retrieve the Ice Dagger, Grimir—their only hope against the relentless Crimson Ravagers. But their journey takes a dark turn when they uncover a truth that forces them to align with old enemies, setting them on a collision course with destiny.

As alliances crumble and secrets unravel, they must confront their deepest fears and make sacrifices that will shape the fate of their world forever. Midnight Embers propels fantasy fans on an epic adventure filled with twists, revelations, and heart-stopping action that will keep them on the edge of their seats until the very end.
