Curse the Dawn - Karen Chance

Curse the Dawn is book four in the Cassie Palmer series. Now it's really getting interesting. Learning to travel ley lines comes in real handy until one splits open and destroys MAGIC headquarters.  Making a deal with a minor god causes Cassie to swap bodies with Pritkin.  Waking up in a man's body, with something she's never dreamed having, is an experience she won't forget :)  Highly recommended.
