Kembral Thorne has a few hours away from her newborn, and she’s determined to enjoy herself at the year-turning ball. But when guests start dropping dead, she can’t help sniffing out trouble—she’s a Hound, after all. Especially when her professional and personal nemesis, notorious burglar Rika Nonesuch, is also on the prowl. Everyone knows you shouldn’t get involved with Echo games. Let alone one involving ancient Echo lords who can turn layers of reality into a gameboard with human lives for pieces. But as the ballroom grows stranger and more otherworldly, it’s clearly too late.

Deep within Gloamingard Castle lies a black tower. Sealed by magic, it guards a dangerous secret that has been contained for thousands of years.

But one impetuous decision will leave her with blood on her hands - and unleash a threat that could doom the world to fall to darkness.

Listen. Claire Bishop is Las Vegas’s greatest stage magician, and she’s perfectly happy with that fame. Ozarik is the next Zaro, the leader of the world’s witches, the modern-day Darcy everyone swoons over.

So, if Ozarik wants to make himself a villain by casting an ultra-dangerous spell to stop death on Earth “for her,” to “protect her,” that sounds like a him-problem. Claire has a show in four hours. Skipping it to save the world might give her manager a heart attack.

When an artifact with the power to wipe out all life in a domain is stolen, Ryx will do whatever it takes to save her home from destruction. But success may demand a larger sacrifice from Ryx than she could have imagined.
