The Good, The Bad, and the Undead
Every Which Way but Dead
A Fist Full of Charms
For a Few Demons More
Meet Rachel Morgan. A witch and bounty hunter for the Inderland Security. She brings in all those otherworldly creatures who have devious plans and actions. She's a good "runner" for the I.S., but it seems like someone is trying to make her disappear. Lately she's only getting the bad jobs tossed at her. Ones that even a 1st year runner could do...and she's not sure why. Soon enough she finds herself in a partnership with Ivy, a beautiful vampire who is as dangerous as they come, and and pixy named Jinks, who can do just about anything. Harrison creates a world that is easy to get lost in and fun to take part with.
I've requested the rest of the series from the library and am waiting patiently for them to be available. As soon as I read them I'll update you. :)
