Book 10, The Unlikely Heroes:
It’s a race to find the Mortal Seven—mortals who had always been able to see magic—before they're murdered. Meanwhile, there’s another crime that needs Liv’s attention: someone wants Father Time dead, and they’ll do anything to draw him out of hiding.

Book 11, The Creative Strategist:
The guardian of the underworld has been awoken, and he’s coming after someone very important—but not if Liv can do something about it.

Book 12, The Born Leader:
The most important magical creature has gone missing, and it’s up to Warrior Liv Beaufont to find him. Liv will die before she allows the God Magician to ruin the world she loves so much. She just hopes it actually doesn’t kill her… or anyone she loves.
