Spell or high water

"The adventures of an American hacker in Medieval England continue as Martin Banks takes his next step on the journey toward mastering his reality-altering powers and fulfilling his destiny. A month has passed since Martin helped to defeat the evil programmer Jimmy, and things couldn't be going better. Except for his love life, that is. Feeling distant and lost, Gwen has journeyed to Atlantis, a tolerant and benevolent kingdom governed by the Sorceresses, and a place known to be a safe haven to all female time-travelers. Thankfully, Martin and Philip are invited to a summit in Atlantis for all of the leaders of the time-traveler colonies, and now Martin thinks this will be a chance to try again with Gwen. Of course, this is Martin Banks we're talking about, so murder, mystery, and high intrigue all get in the way of a guy who just wants one more shot to get the girl."--Amazon.com.
