The Adventurers Guild: Night of Dangers by Nick Eliopulos

After falling victim to a vile betrayal, Zed is cut off from Brock and their friends and unable to warn them about a dangerous enemy on the move. The Adventurers Guild may have defeated the evil that cast the elves from their home, but that doesn't keep them in the Freestoners' good graces for long.

An ordinary day at the market comes to a fatal end when a rare Danger infiltrates the city, leaving over a dozen dead. Tensions come to a boil as the city is threatened by upheaval from within and becomes alight with terror. Brock finds himself frustratingly unable to utilize his underground contacts . . . though the mysterious Lady Grey may not be finished with him yet.

To come together to save their city from a timeless evil looking to settle a score, the young adventurers must learn to trust in each other and be willing to do whatever it takes to stop the tragedy of the Day of Dangers from happening again.
