Ride the storm - Karen Chance

Ever since being stuck with the job of pythia, the chief seer of the supernatural world, Cassie Palmer has been playing catch up. Catch up on the lifetime's worth of training she missed being raised by a psychotic vampire instead of at the pythian court. Catch up on the powerful and seductive forces trying to mould her to their will. It's been a trial by fire that has left her more than a little burned. But now she realizes that all that was just the warm up for the real race. Ancient powers that once terrorized the world are trying to return, and Cassie is the only one who can stop them.
