Hexomancy — Michael R. Underwood

Fan-favorite urban fantasista Ree Reyes and her crew of Geekomancers -- humans that derive supernatural powers from pop culture -- take on their biggest foes yet in this fourth book of the Geekomancy series.

When Ree's long time nemesis Lucretia is finally brought to trial and found guilty for the deadly attack on Grognard's, the Geekomancer community breathes a collective sigh of relief. But Ree and her crew soon discover that Lucretia has three very angry, very dangerous sisters who won't rest until Eastwood -- a fellow Geekomancer -- is killed.

What follows is an adventure packed with epic battles, a bit of romance, and enough geeky W00t moments to fill your monthly quota of adventure and fun.
