Guild of Magic - Jon Auerbach - Bog

Joining the Guild was only the beginning. Now Jen's next quest could spell life or death.
Jen Jacobs thought she was in over her head when she first discovered the secret Quest Board and the world of alchemy and magic hiding just out of sight in New York City. But after a ghost from her mentor Beatrice Taylor's past nearly kills the two of them, Jen finds herself on the cusp of joining the fabled Guild. Except now Beatrice has gone missing, leaving Jen to face the shadowy organization and its 11 members by herself.
If that wasn't enough, the Guild's chairman forces Jen to complete yet another dangerous quest to prove that she belongs: stealing a long-lost vial of Dragon's blood that is the key ingredient to recreating the legendary Philosopher's Stone.
As Jen's past mistakes begin to catch up with her, she'll need to muster all of her ingenuity to survive in the cutthroat world of ancient Relics, magical dynasties, and a possible immortal secretly directing things from behind the scenes.
