The Obsidian Serpent. The Arcane Chronicles, #1

For Lila Grayson, a brilliant and introverted librarian, safety is found in the quiet order of ancient stacks. But her world is shattered when an archaic tome she is cataloging begins to glow, activating a long-dormant spell that reveals a hidden nexus point into the Veil-an invisible layer of reality where magic still breathes. Suddenly, Lila is thrust into a dangerous race against the Collectors, a ruthless black-market organization led by the charismatic Max Donovan, who seeks to hoard magical power for profit.
Rescued by the cynical Ava Sinclair, Lila discovers her family's secret role in the Society of Silent Weavers. Now, Lila must master Lexicraft-the art of speaking and writing reality into existence-to protect an ancient scroll from those who would use it to burn the world down.
