Sequel to the award-winning Order of the Key

Kyp Franklin can't move on. One year after his mother officially declared war against him, Kyp is still struggling to find his feet as the Order of the Key's new leader. He's far too concerned about tracking her down before she causes even more damage than she already has. In fact, that's all he's been doing. Until one day, after a particularly reckless mission, he returns to find a surprising visitor on his doorstep...

Jacklyn Madison can't move on. One year after she left the Order, she has a new team, and a new mission. She's determined to close all the interdimensional rifts between our world and the Dusk, before more people die trying to stop the creatures that pass through them. But a vision she had while on the edge of death leads her to the one place she never intended to return …

Forced to work together, Jacklyn, Kyp, and their respective teams uncover Lavinia's next plan: an alarming mix of magic and science the likes of which has never been seen before. Jacklyn and Kyp must learn to work together again and confront the demons of their past if they're going to stop Lavinia and those assisting her before their larger plan is put into action--a plan that could bring the monsters of the Dusk to our world...forever.
