From California to Colorado, the Old World is filled with complicated women, volatile creatures, and nulls with attitude. This unmissable collection includes the stories that run in between and alongside the Old World novels, allowing readers to catch up with favorite characters and find clues about the future of this bestselling series.

In the never-before-published 'Boundary Blood,' Allison 'Lex' Luther has to accompany her injured aunt on a road trip across the country-but Katia has secrets that could prove lethal even to boundary witches. In the original short story 'The Lost Girls,' Corry Tanger-college freshman, null and sometimes assistant to Scarlett Bernard-has to contend with a new vampire who wants to push all the limits.

It's just another day for Las Vegas healing witch Sashi Brighton (protagonist of Bloodsick), until she gets an urgent call from Los Angeles, kicking off a chain of events that will turn her life upside down in the all-new story 'Powerless.' Finally, 'Nativity' takes us into the delivery room with series lead Scarlett Bernard, who has to juggle her null abilities, new motherhood and a very powerful surprise visitor.

Featuring original bonus materials from Olson's other two series, plus fan favorites 'Malediction' and 'Sell-By Date,' this must-have collection will cast a spell over every admirer of the Old World.
