Winta's Day - Josie Jaffrey

Vampires are hardwired to kill. Is it any wonder that some become experts? 

Jack Valentine is in trouble. The Seekers are living on borrowed time, her ex-girlfriend has gone missing in suspicious circumstances, and someone's sent her a seriously twisted love letter attached to a hanged man. It's not that she doesn't appreciate the sentiment, and sure, the guy deserved everything he got, but even Jack knows that expressions of affection don't usually involve murder. 

It's not the first time Jack's questionable romantic choices have caused problems. Her latest disaster ended with her nemesis, Drake, buggering off to Europe on an extended sexcation, leaving her to face the consequences of the worst walk-of-shame of her life alone. Dealing with that was bad enough, but now her fellow Seekers are poking their noses into Jack's love life in a case that threatens to be their last. 

Jack has two options: toe the line or go rogue. And with her team falling apart around her, rebellion's starting to sound pretty sweet. 

Winta's Day is the third book in Josie Jaffrey's Seekers series, an urban fantasy series set in Oxford, England.
